Technical characteristic of coal-fired boiler under the rule of energy conservation and the reduction of emissions

Abstract

With the increasing requirements of Chinese government to the energy conservation and the reduction of emissions of the coal-fired boiler, Harbin Boiler Company completed the upgrade from the conventional ultra-supercritical pressure boiler to high-efficiency ultra-supercritical and double reheat technology in order to increase unit efficiency and decrease pollution emissions, which better reflected the characteristic from conventional single product to technology integration product. The chapter briefly introduces the achievements on high-efficiency and low-pollution large capacity utility boiler, which Harbin Boiler Company made on the basis of new and integration technology.
