Abstract

The invention provides a coal dust fine combustion heating and cooling combined system, and belongs to the technical field of coal dust combustion and environmental protection. The invention aims to provide a system which utilizes combustion coal dust to prepare steam so as to replace fuel oil, fuel gas and an electrical air conditioner and an electric heater to drive a heating and refrigerating device. The coal dust fine combustion heating and cooling combined system comprises a steam generating device, an intelligent control system and a user, wherein the user comprises a heating pipe net and a cold air pipe net, and the coal dust fine combustion heating and cooling combined system is characterized by comprising an exchange and refrigeration step. The exchange and refrigeration step comprises a heat exchange device and a refrigerating machine, wherein the steam generating device comprises a coal dust refinement processing device 2, a coal dust low nitrogen combustion and fixed sulfur device, a dust control device, a desulfurizing tower and a chimney, and a steam output port of the coal dust low nitrogen combustion and the fixed sulfur device is respectively connected with the heat exchange device and a refrigerating machine in the exchange and refrigeration step through the pipeline; and the intelligent control system is respectively connected with the steam generating device, the exchange and refrigeration step as well as a control end of the user. The coal dust fine combustion heating and cooling combined system provided by the invention has the advantage that the energy-saving and emission reduction effects are notable.

Description

technical field [0001] The invention belongs to the technical fields of pulverized coal combustion and environmental protection, and in particular relates to a fine coal pulverized combustion combined cooling and heating system. Background technique [0002] my country's winter heating equipment for buildings is dominated by coal-fired industrial hot water boilers, with a total capacity of about 1 million MW, an average capacity of about 4 MW, an annual fuel coal consumption of about 300 million tons, and an average boiler thermal efficiency of about 65%. The total heating efficiency is about 50%. Heating coal-fired boilers emit about 5 million tons of sulfur dioxide, about 50 million tons of ash, and about 2.5 million tons of dust every year. There are widespread problems of low efficiency and emission pollution. There is great potential for energy saving and emission reduction. [0003] At present, electric air conditioners are the main refrigeration equipment for buildi...
