In the context of global energy transformation and achieving climate change targets, accelerating the development and utilization of renewable energy such as biomass energy has become a It is a universal consensus and concerted action of all countries in the world. In recent years, my country's biomass power generation and heating technology has developed rapidly, with application areas and scales This document was formulated under the guidance of the "Action Plan for Green, Low-Carbon and High-Quality Development of Boilers", taking full account of the biomass boilers in my country. The application status and development trend of biomass boilers are put forward, including the design, manufacture, inspection and testing, installation and Technical requirements for acceptance, operation, etc. This document complies with the basic safety requirements and energy conservation requirements of TSG11 "Boiler Safety Technical Regulations" and TSG91 "Boiler Energy Conservation and Environmental Protection Technical Regulations". It not only meets the requirements of energy conservation and environmental protection, but also coordinates with the requirements of boiler core construction standards and other general boiler standards. This document aims to help my country innovate biomass energy utilization technology, accelerate the green and low-carbon transformation of boilers and promote high-quality development of the industry. It provides technical support for the safe, energy-saving and environmentally friendly operation of material boilers and their systems, and helps achieve the country's "dual carbon" goals. Technical Specifications for Biomass Boilers

1 Scope

GB/T 44906-2024 is the Chinese technical specification for biomass fired boilers. Burning straw, wood chip, husk and pellet is not the same problem as burning coal, and the standard exists because treating it as though it were is what ruins these boilers: biomass has a high and variable moisture content, low bulk density, and an ash rich in alkali metals and chlorine that slags the furnace and corrodes the superheater at temperatures a coal boiler would find unremarkable. The document sets the classification and the parameters, the requirements on the design of the furnace and the combustion system for the fuel range declared, on the heating surfaces and their arrangement and material selection against high temperature corrosion, on the fuel handling and feeding system, on the ash and slag removal, on the flue gas cleaning and on the control and safety systems, together with the requirements on materials, manufacture, inspection and testing, and the marking and documentation. Its companion GB/T 44907 covers the quality evaluation. For a boiler maker, a plant operator or a specifier in China, this is the governing text.

This document specifies the parameter series and model compilation method of biomass boilers and their systems, fuel, performance, design, auxiliary equipment and systems, Manufacturing, inspection and testing, painting, packaging, marking, nameplate and accompanying documents, installation, commissioning and acceptance and operation requirements. This document is applicable to stationary biomass solid fuel-burning heat exchangers that use water or organic heat carrier as a medium and meet one of the following conditions. Material boiler and its system.

a) Steam boilers with a rated working pressure greater than or equal to

0.1 MPa (gauge pressure) and a rated evaporation capacity greater than 2 t/h;

b) Hot water boilers or organic heat load boilers with a rated working pressure greater than or equal to

0.1 MPa (gauge pressure) and a rated thermal power greater than

1.4 MW Body boiler. The following fixed biomass boilers using water or organic heat carrier as the medium and burning pure biomass solid fuel can be used for reference.

--- Steam boilers (or hot water boilers and organic heat carriers) with a rated evaporation capacity of 2t/h (or rated thermal power of 1.4MW) and below boiler);

---Hot water boilers or organic heat carrier boilers with a rated working pressure of less than

0.1 MPa (gauge pressure).
