1 SECTION ONE - INTRODUCTION Muira Boiler Co., Ltd. began North American activities in 1988 when the manufacturing plant in Brantford, Ontario, was established. Their engineering department developed procedures to meet ASME codes and listing approval from IRI/FM, UL, and pre-approval for the SCAQMD (Southern California Air Quality Management District). The United States corporate sales office, Miura Boiler West, Inc., was established and has developed relationships with national, state, and city inspectors and agencies. The North American network consists of branches in Chicago, Los Angeles, and Ontario. The parent company, Miura Boiler, Ltd. in Japan, is the leading manufacturer of boilers and other thermal equipment in the Pacific Rim holding more than 55% of the market. With factories in five countries, production now exceeds 14,000 units per year. As a result of design necessities in Japan, such as limited space and total dependence on foreign energy, the MIURA STEAM BOILER has been engineered as a highly efficient, vertical water tube, once-through forced-flow design. The MIURA Boiler features a compact unit with a low-water content and is designed to run with a minimum amount of maintenance with simple push-button controls. Operation is quiet, radiant heat losses are minimal, and steam quality is second to none. Miura Boilers are often installed in a multiple boiler network. MIURA Boilers, along with the patented MIURA Multiple Installation panel, allow appropriate horsepower to be brought on and off line quickly to meet sophisticated production needs with maximum fuel economy. The 35-year, field-proven ‘Miura Advantage’ is the ability to reach full output steam from cold start in less than five minutes using the least amount of energy and having the lowest environmental impact. The high efficiency Miura Boiler has won numerous awards from engineering societies and gas associations because it is a compact, safe, cost-effective boiler.

1.1 CODE AND REGULATORY AGENCIES There are a number of codes, standards, laws, and regulations covering boilers and related equipment that should be considered when designing a system. Regulatory requirements are dictated by a variety of sources and are all focused primarily on safety. The equipment shall be installed in accordance with the current regulations, codes, and specifications of the applicable city, county, state, and federal agencies. Authorities having jurisdiction should be consulted before installations are made. For more information on how the various rules affect boiler selection and operation, you may want to contact your local MIURA authorized representative or the engineering firm designing the boiler installation. Here are some essential rules to consider: • The boiler industry is tightly regulated by the American Society of Mechanical Engineers (ASME) and the ASME codes, which control boiler design, inspection, and quality assurance. The boiler’s pressure vessel must have an ASME stamp. (Deaerators, economizers, and other pressure vessels must also be ASME stamped.) • The insurance company insuring the facility or boiler may dictate additional requirements. Boiler manufacturers provide special boiler trim according to the requirements of the major insurance companies. Special boiler trim items usually pertain to added safety controls. Some industries, such as food processing, brewing, or pharmaceuticals, may also have additional regulations that have an impact on the boiler and the boiler room. • UL and /or ASME-CSD1 specifications may be required. State or local authorities may require data on the boiler controls or basic design criteria. • Most areas have established a maximum temperature at which water can be discharged to the sewer. In this case, a blow down separator after cooler is required. • Most state, local, or provincial authorities require a permit to install and /or operate a boiler. Additional restrictions may apply in non-attainment areas where air quality does not meet the national ambient air quality standards, and emission regulations are more stringent. Be sure to investigate this before buying a boiler. • For all new boilers with inputs over 10 Million Btu/Hr, U.S. Federal emission standards apply, including permitting and reporting procedures. 1

• A full-time boiler operator may be required. Operator requirement depends on the boiler’s size, pressure, heating surface area, and volume of water. Boilers can be selected which minimize the requirements, either by falling under the requirements and being exempt, or with special equipment with special equipment that

gives the operator more freedom in the facility. Contact the local boiler inspector for details. • Most states or provinces require an annual boiler inspection. There may be other requirements on piping as well. A partial list of agencies having jurisdiction over boiler installation and operation is given below. This list is comprehensive but by no means all-inclusive. United States Environmental Protection Agency A.S.M.E. Codes and Standards National Board Licensing Requirements American Gas Association Standards Underwriters Laboratories, Inc. Factory Mutual Insurers Industrial Risk Insurers Occupational Safety and Health Administration Food and Drug Administration Local, City, and State Fire Marshall State Boiler Inspection Division Division of Labor and Industry for the Local State or City Local Building and Construction Code Inspectors MIURA Boiler recommends contacting your actual insurance provider as well as the utility companies for assistance in identifying and complying with codes. 1.2 NATIONAL REGULATORY ORGANIZATIONS

1.2.1 MIURA BOILER STEAM GENERATORS (Inspector briefing) The Miura steam generator is an unfamiliar design to most inspectors in the field. The purpose of this section is to address common questions and familiarize the inspector with the Miura steam generator through a general overview of the design and operational characteristics. The Miura boiler EX design consists of straight water tubes between upper and lower annular headers. Both headers are encased in a castable refractory, leaving only the tubes exposed to combustion gases. There is very little water and consequently very little energy stored in the steam generator. Water volume is exclusively in the tubes with only incidental bubbling in the upper header. Therefore, the design has no natural circulation such as a riser, down-comer effect common to natural circulation boilers. Water is forced into the bottom header and tubes by means of a feed water pump. The water is flashed into steam in the tubes, forming a dynamic bubbling system that cools the tubes. This bubbling action may be best described as a “steam gradient,” with more steam at the top of the tubes than at the bottom. Steam is accumulated in the upper header with a final separation in the external separator. Condensate dropped by the external separator is fed back into the lower header. Because of the steam gradient, there is no defined stream/water level and thus no sight glass. Special modifications are incorporated into the boiler construction and safety system to accommodate this. First, probes are inserted directly into the top of the tubes. One probe is long, for low water cut out; and one probe is shorter for feed water control. This water volume control relies on electrical resistance and the bubbling action is what cools the tubes. As the volume of water in the steam generator is consumed, there is less bubbling at the top of the tubes, increasing the amount of electrical resistance. Once the effective electrical resistance reaches a pre-determined level, a ten-second-time delay is tripped, after which the feed water pump is turned on. It continues to run until the bubbles re-establish effective contact with the probe. Should the water volume ever become so low as to lose effective contact with the low water cutout probe, the boiler will shut down. Secondly, probes are inserted into a water column on the side of the boiler. This water control system relies on a conventional electrical conductance system. When water contacts a probe, a circuit is formed. Three probes control the boiler feed; the short probe controls the pump in Low Fire, the medium-length probe controls the pump in High Fire. The long probe is the primary low water cut out. This safety can be confusing for the inspector who encounters the Miura steam generator in the field for the first time, because a water column typically equals a “fixed water level”. This is not true, however, for the Miura EX Series steam generator because of the low water content and the fierce boiling action of the steam gradient. This dynamic system is stabilized by a special modification of the water column to create an artificial level. The flanged pipe leading form the boiler body runs through the column with three holes drilled in the pipe to create an orifice effect. Yet, even with this orifice effect, the artificial “level” formed is not the level in the boiler; and oscillates - especially with load swings on the system. This oscillation is normal and is directly proportional to the volume of water in the boiler tubes. Either of these feed water control systems can operate without the other for proper feed water control. However, the combination of these two systems provides for double low water safety and is called the “two-way water volume control system.” Thirdly, thermocouples are attached directly to the tubes. The thermocouples measure the temperature of the tube and will shut the boiler down if a low water volume condition is detected due to insufficient bubbling, dry fire, or if scale build-up is detected. Scale formation is monitored directly by the rise in tube surface temperature because of lower heat transfer rates. This temperature sensing method can detect a formation of scale of less than 1/64” and will shut down the boiler. The early detection of scale formation is an important factor in maintaining a high efficiency boiler. According to the US National Bureau of Standards, ¼” of scale build upon heating units requires up to 55% more energy to attain the same temperature. Other methods of detecting scale, such as a pressure gage on the discharge of the feed water pump, are much less sensitive. The MIURA XJ1 Intelligent Steam Management microcomputer automatically adjusts the alarm settings for the scale monitor based on current boiler steam pressure and boiler firing rate. 3

The boiler will not operate should any low water safeties fail. Only through tampering could the boiler operate without safeties and develop a dry fire condition. Even in the unlikely event this condition should ever be created, before the tubes superheat enough to destroy the tensile strength of the metal, the amount of energy contained in the remaining water is so small that the possibility of a pressure explosion is negligible. The Miura Steam Generator design has been used for more than thirty-five years with over 200,000 units presently in operation worldwide. There is no record of ANY pressure vessel explosions. Steam is produced within five minutes from cold start-up and selected tubes can be visually inspected through two-inch openings located on the top and bottom headers. A complete inspection is typically accomplished in a thirty-minute period. All Miura EX steam generators are annotated as a forced flow steam generator (with no fixed steam or water level) on the pressure vessel’s P-3 form and registered with the National Board. The complete packaged steam generator is listed with UL as a standard and can be built to IRI, FM and /or ASME-CSD1 at customer request. Please note that all flanges and fittings identified in this manual as 150# ASA comply with ASME/ANSI standard B16.5. The 150# stamping refers to a standard classification not Maximum Allowable Working Pressure (MAWP). As specified in Table A-361 of ASME codes, Section I, 1995 edition, the MAWP for 150# flanges is 205 psig for saturated steam service and 170 psig for Boiler Feed and Blow-off line service. This specification matches the 170psi MAWP rating of the MIURA boiler. Miura is dedicated to reliable and safe operation of its steam generators through sound engineering principles and years of in-the-field experience.
