Scope

This document specifies the general requirements, design conditions, basic steps, and selection of thermal characteristics parameters for the design and selection of gas boiler furnaces and combustion equipment, as well as other requirements related to the design and selection of furnaces and combustion equipment. It also describes the impact of altitude on the design and selection of furnaces and combustion equipment. This document applies to gas boilers that meet one of the following conditions: a) Fixed-type pressurized steam boilers with a designed normal water volume of 30 L or more and a rated steam pressure of 0.1 MPa (gauge pressure) or more; b) Fixed-type pressurized hot water boilers with an outlet water pressure of 0.1 MPa (gauge pressure) or more and a rated thermal power of 0.1 MW or more; c) Organic heat carrier boilers with a rated thermal power of 0.1 MW or more. This document does not apply to cast iron boilers and cast aluminum boilers.
