Low nitrogen gas boiler basically completed the transformation. Strict control of the new urban area of biomass boilers. Biomass boilers should be dedicated boiler, blended prohibit other fuels such as coal, and other supporting efficient dust bag embodiment, non-coal, oil, natural gas-fired boilers and the like directly Burning biomass briquettes.
4, the positive development of central heating. Cogeneration units to increase the technological transformation efforts, speed up the heating pipe network construction, improve the heating capacity and the full release before the end of 2020, phasing out the cogeneration district heating pipe network coverage and high pollution coal-fired boilers in the range. In the area where no cogeneration district heating conditions, a plurality of existing small coal-fired boilers, an alternative construction of large-capacity coal-fired boiler in accordance with the principles of the reduction or the equivalent.
5, deepening the construction of high-pollution fuel combustion zone ban. According to "adjust Yiwu prohibit the use of polluting fuels sales area plan" (Yi Zheng Ban Fa  No. 180) documentation requirements, a comprehensive investigation and eliminate high-polluting fuel facilities within the city, to ensure that no dead ends, no blind spots, Finish high pollution fuel combustion zone ban burning building before July 2019.
6, improve energy efficiency. Vigorously develop, promote energy efficient technologies and products to achieve key energy industries, energy-saving equipment standard full coverage. New energy-intensive projects per unit of product (output) energy consumption should reach the international advanced level. Local conditions to improve building energy efficiency standards, and increase efforts to promote green building, city guide implementation of green building standards for new buildings. Renovation of existing residential buildings to promote energy conservation, encourage rural energy-saving housing.
Gas-fired hot water boiler is a kind of heat device, which uses the heat generated by fuel to release heat to heat the water in the container, so that the water reaches the required temperature (hot water). It consists of boiler body fittings and accessories. The boiler is carried out at the same time in the pot and in the furnace. After the raw water enters the boiler, the heat absorbed from the heating surface of the boiler transfers the heat to feed water, and the water is heated to the temperature to generate heat for the user. The combustion fuel continuously releases heat, and the high-temperature flue gas generated by combustion can transfer heat to the heating surface of the boiler through heat, and the temperature itself gradually decreases and passes through the chimney. The pot works with the stove, an endothermic, An exothermic, perfect fit is a tightly connected and indispensable complete device. Gas-fired hot water boilers are powered by circulating pumps during operation. The heat absorbed by the heated surface is transferred to the raw water continuously, so that the heated surface is fully cooled, and the heated water accelerates the feet so as to ensure that the heated surface of the boiler is safe under high temperature conditions. Work. In order to ensure the quality and safety of the boiler, it is necessary to select the ordinary gas hot water through the boiler produced by the boiler manufacturer to ensure the quality and after-sale service. The gas-fired hot water boiler circulates the hot water of the insulation box through the hot water circulating pump, and repeatedly heats the heat of the water tank. The hot water of the heating pipe is circulating through the hot water circulation pump, and the radiator can reach the heating requirement through the radiator (radiator). Gas-fired hot water boiler and hot water circulating pump cooperate with heat exchanger to realize the dual functions of bath and heating. In a natural circulation hot water boiler, the inlet and outlet water is connected from the upper drum to the upper pipe, the inlet water pipe guides the inlet to the front and lower side of the main pipe, and is heated by the water and raised by the inlet wall tube. The front and back ends of the upper drum are provided with water shields at the boundary between the descending and rising currents, and the baffle blocks only the lower half of the drum's cross-section. For forced circulation, inlet water connection From the front water wall to the upper drum (when the current water wall drop pipe is removed), then transfer to the side water wall below the wall to the side lower pipe, and then to the side. The water wall tube rises to the top drum, and the former convection tube bundle drops down to the bottom drum. Return a number of processes between the upper and lower drums to discharge water from the back end of the upper drum.
