Device carries out plus water supplement.High pressure boiler water supply, it is to the device transmitted to high-pressure fluid, this device characteristic using low-pressure fluid
Pressure cooker high pressure conditions are passed through into the valve on middle container with the low-pressure state for the condenser for leading to air and are connected height respectively
Press pot and condenser, the part that high pressure conditions are separated with low-pressure state.
The steam engine is closer-engines, the piston in cylinder（Or rotor）Vacantly, cylinder inner wall and piston
（Or rotor）Between only exist very narrow gap, it is salable live gas it is again rotatable, do not produce friction with cylinder inner wall, be not required to moisten
Lubricating oil.Steam engine does not need lubricating oil, can just promote its rotary motion to do work with the steam pressure of very little, will not be to steam
Pollute, therefore can directly be recycled after steam condensation.Saturation water in the high-pressure boiler of low pressure heat power generating system steams
Gas need not turn into overheated steam by reheating, and high-pressure boiler structure can be simpler, is steamed in high-pressure boiler without overheating
Steam pipe road reheats to steam, it is not necessary to the somewhat complex design of existing high-pressure steam power plant.
Steam engine is driven using steam power, forms a steam driven heat power generating system, can be at 110 DEG C
And normal power generation is actuated at a temperature of the above, its thermal source can use firepower heating or solar energy heating, and application is wider,
Reach the effect of efficient energy-conservation.
Due to the special construction of the steam engine of use, its driving pressure requires relatively low, and high-pressure boiler is up to more than 110 DEG C
It can drive and carry out normal power generation work, therefore, thermal source can use firepower to heat, and can also be heated using solar energy.It is whole
Individual electricity generation system works in the state of less than 200 DEG C, and the caused more existing thermal power plant of air pressure is low, and danger coefficient is significantly
Reduce, security is higher, lower to the intensity requirement of material, can reduce the cost of power plant construction and maintenance.
Low pressure heat power generating system, recirculation system can effectively recycle water vapour, be sent out with existing thermal power plant
Electric system is compared, and greatly improves thermal transition efficiency, saves cost of electricity-generating.Low pressure heat and power system is belonged to after hydroelectric generation, wind-force
Outside the generating of Generate, Generation, Generator volt, nuclear power, existing thermal power plant, a kind of new, efficient low pressure heat and power system, is existing firepower
Generate, Generation, Generator heat generates electricity, the excellent substitute technology product of solar power generation.
