4365 results about "Condensed water" patented technology

Condensed water is water vapor that has condensed (think of dew on you car window in the morning). This stuff is distilled water a couple of hydrogens and an oxygen. Natural gas at 10 psig and 90F holds 1,100 lbm of H2O per MMCF of gas.

Solar energy and coal-burning unit combined thermal power generation system

The invention relates to a generating system, in particular to the heat generating system consisting of a solar heat collector and a coal-fired unit. The heat generating system adopts solar energy to take the place of the partial coal-fired heat energy of a coal-fired unit boiler. A condenser, an extraction pump, a low pressure heater, a deaerator, a water-feeding pump, a high pressure heater and the heat collector, a coal burning boiler and a steam turbine that are connected in parallel are connected in series. The steam turbine drives the generator and discharges gas into the condenser. Condensed water flows into a heater from the condenser to be heated up and pressurized, is deoxidized by the deaerator, then goes through the solar heat collector to be heated to be saturated vapor and goes into the coal burning boiler or directly goes into the coal burning boiler to become the steam with high temperature and high pressure. And then the steam goes into the steam turbine for applying work to drive the generator to generate electricity. The extracted steam of the steam turbine goes into each heater to finish thermodynamic cycle. The thermal efficiency of solar thermal power generation is improved, investment in the trough solar electrical energy generation of single paraboloid is reduced and the coal consumption of the coal-fired unit is decreased.

Flue gas total-heat recovery device of gas boiler

The invention relates to a flue gas total-heat recovery device of a gas boiler, belonging to the thermotechnical field. In the invention, the temperature of the flue gas exhausted by the gas boiler can be reduced to lower than 40 DEG C by a gas-water heat exchanger and a mixing cooler, then the cooled flue gas is directly supplied for an air-source heat pump water heater for generating the hot water, and the sensible heat and the latent heat in the flue gas can be totally recovered. Most CO2 and NOx in the flue gas can be absorbed by condensed water in the cooling process, thereby reducing the emission of harmful gas. The device comprises the gas-water heat exchanger, the mixing cooler and the heat pump water heater and is characterized in that the flue gas at 150-200 DEG C is cooled to lower than 90 DEG C by the gas-water heat exchanger and then can be cooled to lower than 40 DEG C in the mixing cooler, and the cooled flue gas can serve as heat source to directly enter an evaporator of the air-source heat pump water heater for heat exchange. The invention solves the problems of frosting and low efficiency of the air-source heat pump water heater due to low temperature in winter in the North while recovering the residual heat of the flue gas of the gas boiler at the same time; meanwhile, the emission of the harmful gas in the flue gas of the gas boiler can be reduced, thereby realizing energy saving and emission reduction.
