Novel power-plant raw water and boiler raw water heating system and method

Abstract

The invention relates to a novel power-plant raw water and boiler raw water heating system and method. The novel power-plant raw water and boiler raw water heating method includes that an original system condensation water recycling pipeline is sequentially communicated with a second original system condensation water waste heat recycling heating device, a high-temperature waste heat pump heating device, a low-temperature waste heat condensation water heating device, an original system condensation water desalting device, and a raw water pipeline, and the raw water pipeline is sequentially communicated with a low-temperature waste heat raw water heating device, an original system condensation water desalting device, an intermediate temperature waste heat raw water heating device, the original system condensation water recycling pipeline, the second original system condensation water waste heat recycling heating device, the high-temperature waste heat pump heating device, an original system high-temperature waste heat recycling heating device, and an original system low-temperature deaerating device. According to the novel power-plant raw water and boiler raw water heating method, plenty of waste heat which is abandoned in the environment or applied in an inefficiency mode around power plants or boilers is recycled to heat power-plant raw water and boiler raw water, and principles of consistent temperatures, corresponding grades and stepped utilization are met.

Description

Background technique [0001] At present, the common method of heating raw water in power plants and boilers is to use fossil fuels to heat, but there is often a large amount of waste heat in the surroundings of power plants or boilers that is discarded in the environment or used for inefficient applications, resulting in waste of energy, which does not meet the temperature requirements. , the energy utilization principle of cascade utilization of energy. Contents of the invention [0002] The object of the present invention is: in order to overcome above-mentioned deficiency, provide a kind of method of heating raw water of power plant and boiler; The waste heat is recycled to heat the raw water of power plants and boilers, which conforms to the energy utilization principle of temperature matching, grade matching, and cascade utilization. Description of drawings: [0003] figure 1 It is a schematic diagram of the raw water heating process of the original system; [0004]...
