steam boiler 2t For Sale Laos

To continue to improve urban air quality, to ensure the safety of winter heating, heating Dalian Municipal Construction Committee Office will strictly enforce the "Clean northern winter heating plan (2017-2021 years)" (the "Plan"), and strive to achieve clean heating.

"Plan" put forward, Dalian will gradually increase clean heating rate, adhere to clean coal-fired central heating, local conditions of use of electricity, natural gas, solar energy (3.250,0.04,1.25%), biomass and other clean energy heating, heat storage are encouraged to promote electric heating type and other ways; the existing thermal power plant, waste heat of industrial enterprises depth potential, priority use of heat source heating to achieve ultra-low emissions; research to develop clean energy heating pricing policies; supporting natural gas pipeline network to speed up urban construction, in the implementation of the gas source, guarantee under the premise of residents to use gas, natural gas heating in an orderly way.

Continue to optimize heat distribution. Speed ​​up the construction of heating pipe network, out of network coverage and bulk coal fired boilers within range. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume.

2018, the city built-up area basically integrated heating. 2019, the county level and above the basic integration of urban built-up area of ​​heating. Before the end of 2020, according to the special plan for urban heating requirements, the county level and above in urban built-up area within the range of 300,000 kilowatts and heating cogeneration power plant over a radius of 15 kilometers, coal-fired boiler and does not meet the ultra-low emissions of coal-fired power plants all closed down integration.

2018, above the level of removal of industrial parks and 10 tons of small coal-fired boilers 49 units, 265 units and 10 tons of banned coal-fired boilers since 2014, new registrations. 2019, to improve the standard phase-out of coal-fired boiler, expand the scope to promote the elimination of urban built-up area of ​​20 steam tons / hour (or 14 MW) and coal-fired boilers. 2020, except in accordance with urban heating heating boiler special plans need to retain outside built-up areas at the county level and above cities 20 steam tons / hour (or 14 MW) and coal-fired boilers to be eliminated.

Gradual development of ultra-low emission ultra-low emission coal-fired power plant renovation, started in 2018 and the North Sea thermoelectric thermoelectric Taishan ultra-low emissions renovation, completed in 2019 Heung Hoi coal-fired thermoelectric power plants and other enterprises reform, in 2020 to complete a full ultra-low emission coal-fired plant transformation .

First, the furnace exhaust gas temperature. The higher the exhaust gas temperature, the thermal efficiency is low; and vice versa. Second, the fuel is completely burned. If complete combustion of the fuel can not be done, then the boiler thermal efficiency is very low. Third, heat dissipation furnace wall strength. The stronger the boiler furnace wall heat dissipation, the thermal efficiency is low; and vice versa. Fourth, the amount of scale furnace. The more scale, the worse the situation furnace heat, the thermal efficiency could be reduced.

Explosion-proof door structure: boiler blast doors have Slat (also indemnity for the swing) and blasting membrane two kinds. Slat blast doors, also known as swing-proof door, multi-device to the furnace wall of the combustion chamber. Into its mounted position is inclined and vertical two, by the door, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and should ensure tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas explosion in the furnace or the flue of the boiler, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained.

Gas-fired steam boiler 2t for sale laos there are many different types of places for different use. However, the technical parameters of the boiler is very much the same, in order to allow users to contact the gas boiler steam boiler can be simple and clear to understand some of the details, is a professional manufacturer of large-scale gas-fired boiler, Henan fast boiler This small series of gas-steam the basic parameters of the boiler briefly, after reading these specialized parameters, everyone would know everything.
