This portion of the rules is Intended to cover general descriptions, terminology, and basic fundamentals ol heating boilers, controls, and automatic fuel burning equipment. Because of the wide variety of makes and types of equipment in use. It Is generai in scope.
1.02 USE OF ILLUSTRATIONS
The illustrations used in this Section have been selected to show typical examples of the equipment relerred to In the text and are not intended to endorse or recommend any one manufacturer’s product; nor are the illustrations intended to be used as design criteria or as examples of preferred configurahons of equipment
1.03 MANUFACTURER’S INFORMATiON
For detailed inlormation on any specific unit, the Manufacturer’s information should be consulted.
1.04 REFERENCE TO SECTION IV
The boilers discussed in this Section will be those lim• ited to the operating ranges of Section IV. Heating Boilers. of the ASMI Boiler and Pressure Vessel Code as follows:
(a) steam boilers for operation at pressure not exceeding 15 psI (100 kPa)
(b) hot water heating and hot water supply boilers for operation at pressures not exceeding 160 psi(1 100 kPa) and/or temperatures not to exceed 250°F(120°C)
1.05 GLOSSARY OF TERMS
For terms relanng to boiler design, refer to Section IV, Heating Boilers, Appendix E. Terminology. For terms relating to boiler water treatment, refer to 9.12. Glossary of Water Treatment Terms.
A. Rollers and General Terms
absolute pressure: pressure above zero pressure, the sum of the gage and atmospheric pressures.
accumulator (steam): a pressure vessel containing water and steam that is used to store the heat of steam for use at a Later period and at some lower pressure.
air purge: the removal of undesired matter by replacement wh air.
air vent a valve opening in the top of the highest drum of a boiler or pressure vessel for venting air. Also a device. manual or automatic. that will effect the removal of air from a steam or hot water heating system. It is usually located at the highest point In the system.
allowable working pressure-. the maximum pressure for which the boiler was designed and constructed.
alt itude gage: a pressure gage calibrated in feet. Indicating the height of the water in the system above the gage; usually found as combination pressure, altitude, and temperature gage.
ambient temperature: the temperature of the air surrounding the equipment.
baffle: a plate or wafl for deflecting gases or liquids. base: support for boiler.
beaded tube end: the rounded exposed end of a rolled tube when the tube metal is formed over against the sheet in which the tube is rolled.
belied flsbe end: see flared rube end.
bellows seal: a seal in the shape of a bellows used to pie- vent air or gas leakage.
blind nipple: a nipple, or a short piece of piping or tube. closed at one end.
blowdown: the difference between the opening and closing pressures of a safety or safety relief valve.
blowoff valve: a valve or cock In the bottom and/or near the water line of a boiler, that, when opened. permits free passage of scale and sediment during the blowoff operation.
boiler a pressure vessel that incorporates a fuel input device or mechanism to heat water for space heating or other purposes or to convert water into steam for use in an external distribution system.ASME BPVC.VI pdf free download.
