How to how the selection of industrial what about thermal power station boilers industrial boilers Selection 1, how to determine how to volume and the number of procurement of industrial boiler when the boiler is how to determine the capacity of the boiler is a very significant problem. In general, the capacity of the boiler or output shall be determined according to the area of ​​heating or steam heating requirement in the production process and the use of hot water. First, the user must know the total load range; the second is the peak conditions, including the duration of the peak, the peak frequency, which is the peak period occurs, such as the frequency of occurrence of the peak monthly, weekly, monthly between summer and winter difference between. After considering the capacity and the number of selection device, to calculate the total and peak load requirements. 2, the user how to determine the parameters of steam and hot water steam or hot water should be determined according to the parameters themselves need. Industrial and mining production is mainly required for boiler steam boiler. Steam is mainly used in the production process, it requires a certain temperature to meet the requirements of the production process, such as textile, sugar, rubber, paper, oil and chemical industries. Thus, saturated steam parameters should be determined according to the requirements of the boiler the production process. Advantage is to ensure a constant temperature of saturated steam production required. 3, steam boilers and hot water boilers selected relationship because energy steam heating and hot water heating comfort than steam heating and hot water heating energy requirements. In many industrial and mining enterprises in the production process still requires steam heating, so business users need steam and hot water.

Winter heating season is approaching, Jinan City, Shandong Province in response to the country clean, low-emission environmental requirements, increase efforts to support the promotion of winter heating clean, clean heating to further enhance the city level, issued on the issue clean winter heating engineering and operational capital subsidy Notice.

Second, the use of centralized gas boiler user, uniform implementation of preferential gas prices 1.71 yuan / cubic meter, the heating period and after the end of the third-party audit of gas consumption, gas will be the final settlement price (not exceeding Municipality department approved between the reference price) and 1.71 yuan / cubic meter price difference subsidy to the gas company, to purchase heating companies use non-city franchise gas pipeline business gas heating can be direct subsidies to heating companies.

Third, the use of electricity users centralized heating, heating period and by the end of the third-party audit by the electricity, the power company will operate the unit with the settlement price and preferential rates (level of 0.5 yuan / kwh, Valley Electric 0.25 yuan / kilowatt the difference between the time) subsidy to operate the unit.

Fourth, the use of formula household heating boiler user, purchase subsidy subsidy to the user equipment or units in accordance with Standard 2000 underwritten yuan / household. Temporarily performed using the sub-family user heating boiler gas prices during the step, performed in accordance with a first gear price urban gas prices; after the heating period, gas operation subsidies subsidies to users according to standard 1200 / household .

Fifth, the use of household electric heating type user, can also get subsidies. Subsidy ranges: The air source heat pumps, domestic electric boilers, heating cables, heating the carbon crystal plate user. According to the notification, the device according to the purchase subsidy subsidized purchase truly carbon crystal plate does not exceed 2,000 yuan / household air-source heat pump, domestic electric boilers, heating cables subsidy standard is 2000 Yuan / or household user to Advancer units. After the heating period, power to the user according to operating subsidies subsidies 1200 / standard household.

The level of thermal efficiency natural gas what about thermal power station boilers What is the impact?

The interpretation of the thermal efficiency, we can see, the higher the thermal efficiency of the gas boiler, represents the amount of heat released from the fuel is transferred to the boiler more water, less heat loss, lower fuel costs. In simple terms it can be understood as: the higher the thermal efficiency of the boiler, the lower natural gas consumption.

Why what about thermal power station boiler operation will cause steam temperature change (1) the impact of the steam temperature of the boiler combustion. Furnace combustion conditions change, change directly affects the heating surface of each heat sink share. Administration as discharge changes burner stops, and the nature of the fuel quality, the size of excess air coefficient, and change with the wind mode of the center of the flame, are increased or decreased on the steam temperature has a great influence. Effect of steam temperature (2) of load change. Superheater, reheater thermal characteristics determines the size of the impact load to the steam temperature change, joint superheater currently widely used, the use of convection and radiant superheater two different thermodynamic characteristics, so that steam temperature by Effect of boiler load change is small, but still generally close convection properties, the boiler load increases as the steam temperature is reduced correspondingly raised, lowered. Impact on the steam temperature (3) steam pressure changes. The higher the vapor pressure corresponding saturation temperature higher; conversely, the lower. Thus, as a result of a disturbance of the steam pressure has a more substantial increase or decrease, the steam temperature will be correspondingly increased or decreased. (4) water temperature and desuperheating steam temperature influence on the amount of water. In drum boiler, the feed water temperature is lowered or raised, anti steam temperature can be raised or lowered. Size desuperheating water flow more directly influence the steam temperature drop, lift. (5) Effect of temperature on the high-pressure cylinder exhaust steam of the reheat steam temperature. Reheater and export steam temperature is as high pressure cylinder exhaust steam correspondingly increases the temperature of the lift, it decreased.
