The hotel washing plant with a steam boiler Why superheated steam results were better? Under pressure steam boiler, water is heated to be softened, the water temperature is gradually increased, and finally reached the boiling point, is called saturated steam temperature is known as the saturation temperature. Saturation temperature and pressure of the steam boiler is related with the rising pressure, saturated steam temperature is relatively increased, and the steam temperature and pressure is directly proportional. Superheated steam boiler is a steam boiler in the case of constant pressure, saturated steam reheating temperature of the steam will be increased accordingly, referred to as superheated steam boiler. Than the saturated steam superheated steam washing plant is good for effect, because of the water content in the saturated steam superheated steam is relatively higher than in the water content, while washing plant dryer and ironing machine is required temperature , the higher the better quality steam will save some fuel.
First, the premix
The main heat loss of condensing power plant is that the heat of steam turbine exhaust is taken away by cooling water in condenser and can not be utilized. This part of heat loss usually accounts for 40% ~ 60%, so the efficiency of condensing power plant is not high. If the steam exhaust or exhaust steam of steam turbine is used for heating, the steam loss of steam turbine can be greatly reduced, and the energy utilization rate can be greatly improved by replacing the low efficiency and small boiler with high efficiency and large capacity boiler, if the steam exhaust or extraction steam of steam turbine is used for heating by the way of co-generation of heat and power. Therefore, great economic benefits can be obtained. It can be used to build large-scale thermal power plant, retrofit condensing power plant, heat supply and small and medium-sized thermal power plant provided by enterprises and other ways of co-generation.
It is reported that in March 28, the Office of the ecological environment in Gansu Province on environmental governance ecology, held a press conference. Will be mentioned in: 2019, Gansu Province will improve air quality for the goal, to strengthen air pollution control work. 2019 air pollution prevention and control measures are: to adjust the energy structure, clean winter heating in an orderly way, and then completed more than 400,000 rural residents warm Tukang years Tuzao, small stove coal to gas, coal to electricity or clean coal replacement project; built a sound 86 counties (cities, districts) focused on coal distribution system, formulate issued "the province's reservoirs (for sale) coal yard special clean-up remediation work plan" to carry out the coal market, coal quality control special inspection inspection, serious investigated sales of low quality coal, coal yard dirty and messy and other issues.
1, adjusting the industrial structure, the implementation of "scattered pollution" enterprise remediation special action, complete ban before the end of the relocation, renovation work; continue to promote urban built-up area of heavily polluting enterprises relocation, renovation or off exit, according to the law to promote backward production capacity in accordance with regulations can quit, support and foster a number of competitive energy-saving and environmental protection enterprises.
2, accelerate the implementation of the transformation of ultra-low emissions of thermal power, steel and other key industries, before the end of the year plans to complete within 10 coal-fired thermal power ultra-low emission renovation (except long discontinued); implementation of key enterprise organized, unorganized emission control standards by the end of before the completion of discharge standards smelting production company boiler.Free Chat
