Standards Development
This technical specification stipulates the terminology of comprehensive combustion performance of SRF, proposes comprehensive performance testing and sampling methods, and other related content. It is applicable to all kinds of SRF and can be referenced by various incineration facilities.
For different kilns and furnaces using SRF, there are significant differences in their requirements for the combustion characteristics of SRF. Taking coal-fired power generation boilers and cement kilns, which are the most application scenarios for SRF, as the example: The residence time in coal-fired boilers is short, and it is required that there is no reignition after the furnace outlet to avoid overheating of the heating surface. Therefore, it is hoped that the combustion time of SRF will be short. In addition, there may be high and low load changes in the boiler. At low loads, there will be insufficient fuel supply and low furnace temperature, and SRF is also required to be easily ignited to ensure stable combustion. Relatively speaking, cement kilns have large thermal inertia, long residence time in the furnace, and stable thermal load. Therefore, the requirements for the combustion characteristics of SRF, such as ignition and burnout, are relatively not strict. And other furnace types also have different requirements for SRF combustion characteristics based on their own combustion organization and structural design. However, due to the lack of standards on combustion characteristics as a key indicator, existing technical standards cannot provide effective guidance and requirements for manufacturers, product suppliers, market regulatory agencies, and users. Based on the current background, it is necessary to establish SRF technical specifications for combustion characteristics to guide the further application of SRF.
