After the recent years, increasing environmental pressures and an increasingly serious energy crisis, the government has introduced a series of laws and regulations on the promotion of energy conservation and emission reduction, to encourage new energy promotion, and gas-fired attention and widely used, broke the burning coal industrial use boiler "thriving" situation. With respect to polluting coal-fired boilers and oil-fired boilers, gas boilers use of clean energy - natural gas, less pollutant emissions, higher energy efficiency, in general, more cost-effective. Here follow the fast boiler together to understand the pros and cons of specific natural gas boiler it.
Qinhuangdao City Funing District Branch of Ecological Environment Agency organized the key enterprises responsible person within the jurisdiction of the industrial use boiler demolition, renovation work will hold a special schedule. The meeting stressed the need to vigorously promote coal-fired, gas-fired boiler demolition, renovation work progress, continued to improve ambient air quality.
At the meeting, staff of the Office of atmospheric area of the current coal-fired, gas-fired boiler demolition, renovation progress has been informed. Up to now, boiler demolition and reconstruction of the region involved all disabled.
First, Funing District compressed air quality improvement increasingly smaller space, air pollution prevention and control situation is very serious, involving various enterprises must attach great importance to effectively assume responsibility for environmental protection.
Second, the coal-fired boiler in accordance with the "water power, chimney down, shifting the body" standard transformation and low nitrogen oxides emissions analyzer mounted nitrogen gas boiler work requirements, make sure the end of this completed, the embodiment late cut-off regulation.
Third, the Bureau of atmospheric sciences, environmental law enforcement unit to further strengthen law enforcement and inspection and supervision, the monitoring center to provide scientific data monitoring, to crack down on environmental violations, it is important to ensure that coal-fired, gas-fired boiler demolition, renovation work is completed on time.
Select the first steam industrial use boiler to know what parameters? Steam boilers have the following main parameters: 1, Rated evaporation Rated evaporation is power steam boiler, steam boiler is the most important parameter, usually expressed in tons evaporation, that is, we usually say how many tons of boiler. 2, rated steam pressure rated steam pressure means that the steam pressure generated in the steam boiler, generally expressed in MPa or kg. 1MPa is 10 kg, like laundry, all hospitals, factories and the like conventional steam occasions the general use of low-pressure steam 1.0MPa or less. Only when using steam as a power to require the use of high-pressure steam. 3, where the steam temperature of said steam temperature, refers to the temperature of saturated steam. Saturated steam pressure and steam temperature are corresponding. Temperature of saturated steam at a pressure of 1MPa 184 ℃. 4, gas / oil / coal consumption fuel consumption is an important indicator of concern when choosing a steam boiler, which is directly related to the use of the running cost of the boiler. In the operation of the boiler, the fuel cost is very impressive, if just considering the purchase cost of buying a cheap but high energy boiler, which led to the late high operating costs, certain that it will be wasted. 5, the thermal efficiency of fuel consumption with the boiler thermal efficiency of boilers is inversely proportional. The higher thermal efficiency, lower fuel consumption of the boiler. Boiler thermal efficiency expressed as a percentage, the value is a more intuitive. 6, the boiler operating weight, size or location in the election of the steam boiler, it should find the place whether the load per unit area can withstand the weight of the steam boiler, and if there is enough space to place the steam boiler maintenance and reserve space.
Coal-fired industrial use boiler economizer economizer effect to save the name suggests is a secondary member of coal fired boilers and the like for the device, the principle is to use the coal-fired boiler economizer flue gas heat exchanger for heating the feedwater. Economizer heat absorbing smoke, reduced exhaust gas temperature, by improving the thermal efficiency of coal-fired boilers, to achieve the purpose of saving coal. Secondly, in the coal-fired boiler feedwater into the drum, since the exhaust gas after the preheating heater temperature increased, reducing the temperature difference between upper and lower walls of the drum, the drum reduces the thermal stress of the upper and lower walls coal-fired boilers, to reduce the vertical drum wall temperature difference due to damage, protect the safe operation of coal-fired boilers, coal-fired boilers to extend the life of the road.Free Chat
