In recent years, my country's biomass power generation and heating technology has developed rapidly, and the application areas and scale have continued to expand. There are many kinds of fuel and combustion methods, and the quality and performance of products vary. This document is guided by the "Action Plan for Green, Low-Carbon and High-Quality Development of Boilers". Next, from the actual development and application of biomass boiler technology in my country, as well as the successful practice of biomass boiler design, manufacturing, inspection, installation, operation, etc. Based on the practice and taking into full consideration the characteristics of biomass resource utilization in my country, a product quality evaluation index system based on the whole life cycle of biomass boilers was constructed. Standardization system and evaluation method. This document complies with the basic safety requirements and energy conservation requirements of TSG 11 "Technical Code for Boiler Safety" and TSG 91 "Technical Code for Boiler Energy Conservation and Environmental Protection". Energy and environmental protection requirements, and in line with the core construction standards of boilers, general product standards, and the requirements of GB/T 44906 "Technical Specifications for Biomass Boilers" Coordinate. This document serves as the basis for the evaluation and certification of the quality and performance of biomass boiler products, and is of great significance in guiding the technological innovation of biomass boilers and improving the quality of biomass boilers. The safety, energy-saving and environmentally friendly operation level of boilers, the continuous promotion of green, low-carbon and high-quality development of boilers, and the realization of the "dual carbon" goals are of great significance. Important significance. Technical criteria for quality and performance evaluation of biomass boilers

1 Scope

GB/T 44907-2024 sets the criteria for evaluating the quality and performance of a biomass fired boiler, the companion to the technical specification GB/T 44906. It is the document a purchase or an acceptance is settled against, and it is written around the property that makes a biomass boiler difficult to buy: its performance depends on the fuel, so a guarantee is meaningless unless the fuel it applies to is defined. The standard sets the evaluation indicators and their calculation, covering the thermal efficiency and the method by which it is determined, the output and the ability to hold it across the declared fuel range, the combustion efficiency and the unburnt carbon in the ash, the emissions of particulate, nitrogen oxides, sulfur dioxide and carbon monoxide, the auxiliary power consumption, the availability and the reliability, the slagging and fouling behaviour, and the safety and control functions, together with the test conditions, the measurement methods and the grading of the result. For a purchaser, a manufacturer or a testing body in China, this is the evaluation text.

This document specifies the technical indicators, evaluation methods and compliance requirements for the quality performance evaluation of biomass boilers. This document applies to stationary biomass solid fuel biomass heat exchangers that use water or organic heat carrier as working fluid and meet the following conditions 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 and organic heat 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 Carrier boiler.
