"To denitrate, we must first consider the optimization technology of combustion in the furnace. At present, many boilers, especially those used by small and medium-sized enterprises, have unstable combustion efficiency and high emission concentration. " William said, "Through the transformation in the furnace, it can not only help it to denitrate, but also improve its combustion efficiency and save operating costs. For such enterprises, denitrification not only costs nothing, but also saves money. "
William introduced aminah's first successful transformation case in China, namely, the boiler transformation of Yixing Xielian Thermal Power Co., Ltd. According to reports, the boiler type of this enterprise is a tangentially fired boiler, and the designed coal type is bituminous coal. Single machine capacity 1.35 MW, with a total capacity of 270 MW. The emission of nitrogen oxides before transformation is 520 mg/m3.
In order to achieve the best transformation effect, Amina first comprehensively evaluates the recent operation of the unit, and then uses the CFD analysis tool patented by the company to simulate and compare the working conditions before and after the transformation and optimization. The calculated data can be used to evaluate the influence of various boiler transformation schemes. Generally, the total amount and position of fuel and air entering the furnace will change.
