With the rapid rise of manufacturing industry, the problems of resources and environment become more and more prominent. How to achieve sustainable economic and social development has become a realistic issue of great concern to the whole society. As a strategic emerging industry, Heilongjiang Kangtai Industrial Investment Management Co., Ltd. has higher requirements for environmental protection, energy saving and energy consumption reduction of boilers. Circulating fluidized bed combustion technology, as a new and mature clean coal technology with high efficiency and low pollution, has many advantages that other combustion methods do not have. It belongs to low temperature combustion, and the emission of nitrogen oxides is much lower than that of pulverized coal fired boilers. Therefore, circulating fluidized bed boilers have become the first choice of new combustion technology boilers with high efficiency and low pollution. Kangtai's choice of SHX series circulating fluidized bed hot water boilers conforms to the environmental protection policy of energy saving and emission reduction in China.
