Abstract

The invention discloses a combined heat and power generation system and a heat supplying method in the technical field of combined heat and power generation. The combined heat and power generation system comprises a boiler (1), a turbine high-pressure cylinder (2), a turbine intermediate-pressure cylinder (3), a turbine low-pressure cylinder (4), a generator (5), a condenser (6), a cooling tower (7), a directly-connected heating network system (8), a water circulating pump (9), a peak boiler (10) and a thermal power plant heat regenerative system (11). With the adoption of the combined heat and power generation system and the heat supplying method, the exhaust steam heat of the power station steam turbine is recovered; the energy grade waste caused by steam extraction and heat supplying with unreasonable parameters at present can be greatly reduced, and the overall energy saving of the combined heat and power generation system can be achieved. According to the invnetion, difference between the return water temperature and the heating temperature is low; and a large-scale distributing type variable frequency pump directly-connected heating network system can be applied for the generation system. The maximization of energy-saving and emission-reducing benefit can be achieved, and the interaction between thermal load and power load in the combined heat and power generation system is relieved.

Description

technical field [0001] The invention belongs to the technical field of heat and power cogeneration, and in particular relates to a heat and power cogeneration system and a heat supply method. Background technique [0002] The heating system is composed of heat source, heat network and heat users. The theoretical combustion temperature of coal and other fossil energy at the heat source is above 1000°C. As far as heating is concerned, most of the current low-grade heating cogeneration systems in my country adopt steam extraction heating mode, and the popular hot water heating network system supplies The return water temperature is generally 95°C / 70°C (low-temperature hot water heating system) or 130°C / 70°C (high-temperature hot water heating system), while the temperature required by heat users is only around 20°C. The energy grades of heat users are seriously mismatched. As far as the current technical level is concerned, the current combined heat and power system still has de...
