1 Scope

GB/T 17954-2025 is the Chinese national standard on economical operation of industrial boilers, in the field of energy and heat transfer engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 2 December 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 July 2026. Classification: ICS 27.010, CCS F01. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the basic requirements, technical indicators, and comprehensive evaluation for the economical operation of industrial boilers. This document applies to stationary boilers that use coal, oil, gas, or biomass as fuel or electricity as a heat source and water or organic heat transfer medium.

a) Steam boilers with a rated steam pressure of

0.1 MPa <=

b) Hot water boilers with a rated outlet pressure >=

0.1 MPa and a rated thermal power >=

0.1 MW;

c) Organic heat carrier boilers with rated thermal power >= 0.1MW. Non-power generation steam boilers with a rated steam pressure >=3.8MPa shall follow this procedure.
