Discussion on Approach to Renovation of Industrial Coal-Fired Boilers in China

This paper analyzed the present status of industrial coal-fired boilers and relevant policies and standard requirements, and had in-depth discussion on alternative ways of industrial coal-fired boilers, pollution control and management optimization for energy saving. It pointed out that options for elimination and replacement of industrial coal-fired boilers are new energy high efficiency boilers, industrial waste heat utilization, heat pump, new energy and renewable energy. For pollutant control, it provided feasible technologies on controlling dust, sulfur dioxide and nitrogen oxides respectively. Energy conservation measures including evenly hierarchical coal feeding technology, low nitrogen high efficiency combustion technology and etc. are stated as well. It ends up with brief analysis of relevant necessary supporting measures for the whole renovation scheme.
