The invention discloses a high-parameter waste incineration waste heat boiler reheat steam heating system comprising a boiler barrel, a primary separator, connecting pipes, reheater heat exchange equipment, a secondary separator and a superheater introduction pipe. The primary separator is arranged in the boiler barrel. The reheater heat exchange equipment is fixed above the boiler barrel through the multiple connecting pipes, the secondary separator is arranged above a heat exchange pipe in the reheater heat exchange equipment, and the superheater introduction pipe is arranged on the part, above the secondary separator, of a reheater heat exchange equipment shell. According to the high-parameter waste incineration waste heat boiler reheat steam heating system, the external reheat steam heat exchange system is adopted, all saturated steam generated by the boiler barrel is introduced into the reheat steam heat exchange equipment to heat reheat steam, the saturated steam is introduced into the superheater after heat exchange, so that the heating quality of the reheat steam of the boiler can meet the requirement under the working conditions of normal load and variable load of the boiler, stable operation of a boiler reheating system can be effectively guaranteed, the power generation efficiency of a power plant is guaranteed, and meanwhile the problem of corrosion of a heat exchange tube bundle in the boiler is avoided.
Description
technical field [0001] The invention belongs to the technical field of waste incineration power generation boilers, and in particular relates to a high-parameter waste incineration waste heat boiler reheating steam heating system. Background technique [0002] At present, in order to improve the power generation efficiency of waste incineration power plants, it is necessary to continuously improve the main steam parameters of waste incineration waste heat boilers and design the reheat steam circuit at the same time; however, there are large load fluctuations in waste incineration waste heat boilers, and the arrangement of reheat steam tube bundles in the furnace is easy to corrode question. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and provide a high-parameter waste incineration waste heat boiler reheat steam heating system, which adopts the reheat steam heating method outside the furnace to solve the corrosion a...
