GB/T 44906-2024 Technical specifications for biomass fired boilers
1 Scope
This document specifies the parameters and model numbering method, fuel, performance, design, auxiliary machinery and systems, manufacture, inspection and test, painting, packaging, marking, nameplate, and accompanying documents, installation, commissioning and acceptance, as well as operation requirements for biomass fired boilers and their systems.
This document applies to stationary pure biomass solid fuel fired boilers that meet one of the following conditions and also use water or organic fluids as media, as well as their systems:
a) Steam boilers with a rated working pressure of 0.1MPa (gauge pressure) or higher and a rated evaporation capacity of more than 2t/h;
b) Hot water boilers or organic fluid boilers with a rated working pressure of 0.1MPa (gauge pressure) or higher and a rated thermal power of more than 1.4MW.
For the following stationary pure biomass solid fuel fired boilers that use water or organic fluids as media, this document may be used for reference:
——Steam boilers (or hot water boilers and organic fluid boilers) with a rated evaporation capacity of 2t/h (or a rated thermal power of 1.4MW) and below;
——Hot water boilers or organic fluid boilers with a rated working pressure less than 0.1MPa (gauge pressure).

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 2900.48, GB/T 34348 and NB/T 47034 as well as the following apply.
3.1
biomass
various organisms produced through photosynthesis
Note: In this document, biomass mainly refers to various agricultural residues, forestry residues, energy crops, and their processing residues, etc., and does not include industrial organic solid waste and municipal solid waste.
3.2
hard stalk and woody plant
collective term for relatively hard biomasses such as the stalks of cotton, soybeans, and other agricultural crop residues, tree branches, wood processing materials, or waste materials
3.3
straw and non hard stalk
collective term for relatively soft biomasses such as the stalks of corn, wheat, rice, sorghum, and other herbaceous plants
3.4
biomass molded fuel
molded fuels with a certain shape (mostly regular shapes such as cuboids or cylinders), specific dimensions, high bulk density, and are conducive to transportation and combustion, which are processed using woody and herbaceous plants and their waste materials as raw materials, through densification and molding technology
3.5
biomass fired boiler
a boiler that uses biomass as fuel
