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] like 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 re...

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 present invention involves a steaming Langken-ammonia steaming Langchen joint recycling power generation device, which is specific to the technology field of thermal power equipment in thermal power plant. Background technique [0002] The fire power plant with water steam as the working quality is a factory that transforms thermal energy into mechanical energy and transforms mechanical energy into electrical energy.The cycle of the application of the power plant is very complicated.Enter the boiler, heat and vaporize in the boiler, and form a high -temperature and high -pressure overheating steam. The overheating steam expands and does it in the turbine to become a low -temperature and low -pressure lack of steam.Water is sent to the boiler for a new cycle.As for the complex cycle used by thermal power plants, it is just based on the Langken cycle, a new cycle of heating cycle formed in order to improve thermal efficiency and improvement, and the heate...
