Problems solved by technology
[0006] The Kalina cycle power generation technology mentioned above also has its inherent disadvantages: For example, ammonia is flammable, explosive and toxic. When using the waste heat of flue gas to organize Kalina cycle power generation in the tail flue of boilers or industrial furnaces, it must To consider the leakage caused by dust in the flue gas caused by wear and corrosion of the heat exchanger arranged in the flue, it is necessary to consider the resulting explosion protection and the protection of the environment and working place; the ammonia-water mixture as the working medium Karina cycle, ammonia in ammonia water is a flammable, explosive, toxic medium

Embodiment 1
[0035] Such as figure 1 Shown, a kind of steam Rankine-ammonia steam Rankine combined cycle power plant, this device comprises steam Rankine cycle, ammonia steam Rankine cycle system, specific embodiment is as follows:
[0036] The steam Rankine cycle refers to the saturated steam 2 coming out of the boiler body 1, passing through the heater 3 to form superheated steam 3-1, and sending it into the steam turbine 4 to drive the steam generator 21 to generate electricity; the exhaust steam 5 coming out of the steam turbine 4 enters Condensation evaporator 10 forms condensed water 6, which is sent to boiler body 1 through condensed water pump 6-1, deaerator 7-1, feed water pump 7, and feed water heater 8, and then generates saturated steam to form steam Rankine loop loop.
[0037] The described ammonia vapor Rankine cycle refers to that the ammonia liquid 11 returns to the ammonia condenser 18 through the regenerator 15 and the return line 19 through the circulation pump 12, the...

The invention relates to a vapor Rankine-ammonia vapor Rankine combined cycle power generation device. A condenser for the vapor Rankine cycle serves as an evaporator for the ammonia vapor Rankine cycle; a plenty of latent heat of vaporization released through the vapor condensation is used for the efficient ammonia vapor Rankine cycle power generation by utilizing the characteristic of higher utilization efficiency of an ammonia vapor Rankine cycle system for a medium and low temperature heat source; more than 50 kilowatt hours per each ton of the vapor can be recycled only by utilizing the latent heat of vaporization of the vapor of the vapor Rankine cycle for the power generation; at the same time, the safety difficulty of recycling the afterheat of the smoke through the ammonia Rankine cycle is solved, the temperature of the exhaust smoke is reduced efficiently, and low-temperature corrosion of the smoke is avoided. The vapor Rankine-ammonia vapor Rankine combined cycle power generation device not only can be used for energy-saving reconstruction of the conventional machine set, but also can be used for the design and construction of newly built machine sets, and has remarkable economic, social and environmental protection benefits.
Description
technical field [0001] The invention relates to a steam Rankine-ammonia steam Rankine combined cycle power generation device, specifically belonging to the technical field of thermal power plant power devices. Background technique [0002] A thermal power plant that uses water vapor as a working medium is a large-scale factory that converts thermal energy into mechanical energy, and then converts mechanical energy into electrical energy. The cycle applied in power plants is very complicated, but in essence, it is mainly completed by the Rankine cycle composed of boilers, steam turbines, condensers, water pumps and other equipment. The working principle is: the feed water is first pressurized by the feed water pump and then sent Into the boiler, the water in the boiler is heated and vaporized to form high-temperature and high-pressure superheated steam. The superheated steam expands and does work in the steam turbine and becomes low-temperature and low-pressure exhaust steam....
