Gas hot water steam temperature boiler in thermal power station which has energy-saving measures in the heating hot water boiler heating boiler is the main force for how gas hot water boiler energy problem, we summarize some of the energy-saving measures, there is a need for a reference for a boiler unit. First, both the steam pipe insulation pipe, hot water pipe or a variety of devices with a number of heat pipes are more or less heat loss in the heat transfer process, therefore, it is necessary to transfer thermal insulation pipes; addition to the insulate the pipe to a certain extent also played a role in the protection pipe. In the choice of heat insulation material, to the following requirements. 1, to select a high thermal conductivity and good heat insulating properties of the material. 2, when the heat medium temperature greater than 120 deg.] C, and the insulation material should not contain organic combustibles; only when the medium temperature is below 80 ℃, before selection of insulation material containing organic matter. 3, less hygroscopic insulation materials, does not cause corrosion of the wall, easy to manufacture and have a shape, easy to install performance advantage. The thickness of the insulation layer is determined according to the following general principles. 1, to ensure that heat losses in the pipe a predetermined value or less, not exceed a predetermined value range. 2, the surface temperature of the insulation should not exceed 55 ~ 60 ℃. 3, insulation capital investment should be controlled at the cost of insulation and heat loss equivalent to the cost of fuel and less. It is noted that to minimize the heat loss of the heat transfer conduit, the pipe diameter should be as small as possible, and shorten the transportation distance, while it should be relatively small pressure drop. Of heating equipment and pipelines good insulation is an important energy-saving measures. Second, hot water heating effect is relatively better in comparison with other media, the use of hot water heating can save 20-40% of the fuel, since the hot water heating and does not produce secondary condensed water evaporation losses. Secondly, both steam and hot water heating pipes compared to heating pipes, heat loss caused by the former will be smaller because of the need for continuous blowdown steam boilers and regular sewage, while the hot water boiler requires only a small amount of sewage on a regular basis. Then, according to the change Boilers indoor and outdoor ambient temperature flexibly adjust the hot water temperature is provided, on the premise of ensure the quality of the heating, the purpose of saving fuel. Third, the full absorption of flue gas waste heat boiler flue will continue to exclude a large number of high-temperature flue gas, which will be part of the flue gas heat away into the atmosphere, causing heat loss. Therefore, the high temperature flue gas heat recovery, is an effective energy-saving measures at boiler heating. Fast boiler gas hot water boiler of painstaking research, launched condensing gas hot water boiler thermal efficiency of up to 108%. By adding recovery near the boiler flue condensation, latent heat of the high temperature portion of the heat collected flue gas, into the boiler for reuse, higher thermal efficiency, fuel will be reduced relative to the investment cost.
As a type of gas fired steam temperature boiler in thermal power station , WNS gas fired steam boiler is designed in three-pass flame tube/smoke tube structure with the rated evaporating capacity of 1-20 ton.The horizontal gas fired steam boiler for sale is characterized by a very compact construction.
Third, reduce staff. Less than coal-fired gas steam temperature boiler in thermal power station auxiliary boiler equipment, needed less staff, the burden of the cost of wages and benefits will be a lot less.
