"Henan 2018 campaign of air pollution control plan" recently introduced, to guide and encourage medium-sized coal-fired electric hot water boiler supplierss eliminated. In the province's foundation 10 steam tons / hour and the coal-fired boiler Chaigai, and gradually expand the boiler removal and clean energy transformation of coal-fired range, before the end of 2020, the basic elimination of provincial cities planning area 35 steam tons / hour and coal-fired boilers.
Financial awards complement the way:
1, the completion of the coal-fired boiler Chaigai before the end of October 2018, giving not less than 60,000 yuan / tons of steam financial awards complement;
2, the completion of the coal-fired boiler Chaigai before the end of October 2019, giving not less than 40,000 yuan / tons of steam financial awards complement;
3, the completion of the coal-fired boiler Chaigai before the end of October 2020 no longer give financial awards complement.
Further, out of the boiler removal methods include eliminated, an alternative centralized heating boiler, coal gas, coal to electricity, use geothermal, wind, solar, biomass with baghouse, clean coal to burn not including , CWS, anthracite, semi-coke, green coke, crude oil, coal-fired boiler removal must be removed chimney or flue physical cutting, it does not have the complex production conditions. Do not use has been shut down, eliminated waste coal-fired boilers to cash rewards and subsidies. In the process of new coal-fired boilers to switch to natural gas to be synchronized to achieve low nitrogen transformation.
Two methods decontamination mounted electric electric hot water boiler suppliers recent introduction of a new electric boiler in the market, its own heater decontamination, manifolds for supply and return pipe connection brightest feature heated water and sinks water, which normally consists of three sub-manifold portion trap, manifold and mounting bracket composed, per trap effect after the introduction of each separate heat source hot water passage pipe, is to separate the cooling sump cold water inside to bring together all the way. Automatic exhaust valve when the air in the system, accumulation of gas in the upper portion of the exhaust valve, in vivo accumulation of the bubbles so that float drops with the water level, thus opening the exhaust piston; After gas drained, the water level rises, the float will also rise , closing the exhaust piston. As the cap is screwed tight valve body side portion, the exhaust valve to stop the exhaust gas, in general, the bonnet should be in an open state, the expansion tank is an important component of central hot water heating system and air-conditioning water system, its role is housed and expansion shrinkage compensating system water. The expansion tank is generally located at the highest point of the system, it is typically connected to the vicinity of the circulating pump (pump central air chilled water) suction inlet and return water pipes. The electric boiler is usually the size of decontamination decontamination installation has the following two methods: 1, installed in the station. Decontamination station generally larger, or attached to the return pipe before a heater, in order to prevent debris flowing into the heater; 2, mounted on the water supply pipe outside the station. Decontamination station at the well outside the home are generally small, usually mounted on the water supply pipe, installed some systems, some systems are not installed, its role is to prevent debris entering the user's radiator.
In order to ensure the safety of the fuel-fired boiler, its weekly inspection is indispensable, and there are nine items to be inspected each week. 1. The ultra-low water level shut-down test should be carried out. According to the button on the control board, the function of the ultra-low water-level shutdown should be checked by simulating the lack of water or discharging the water. 2, the safety valve manual opening test, reset should be rapid. 3, the burner control system and the electric eye should be checked, the photoelectric tube of the electric eye should be taken out, the furnace should be stopped inside, and the electric eye should be cleaned. 4, valve root filling or replacement to eliminate run-and-run leakage. 5, bolt fastening, especially gas pipeline system, if necessary, leak detection. Clean the oil filter of the oil-fired boiler every month, the decontamination device on the oil path, the filter on the gas line. 7, maintain every six months. Check pressure gauges and cleaning gauges. 8, maintain the water level electrode, take it out and grind it with fine sand paper. 9, clean the flue, generally according to the exhaust temperature to determine whether to clean up, the general situation Under the condition that the exhaust temperature does not exceed that measured at the outlet of the boiler and the population of the flue, the scale is increased and the efficiency of the boiler is reduced, so it must be cleaned up. Oil-fired boilers, in particular, need to be cleaned up regularly. On the one hand, it is for the sake of economic consideration, on the other hand, it is also due to safety considerations (bad heat conduction of smoke, easy to cause local burnout). When cleaning and replacing asbestos liner, we should adopt the method of staggered mouth lap (preventing smoke from running out), apply graphite, not add lubricating oil. 4) after boiler repair or annual inspection, check manhole, head hole, hand hole nut should not loose, To check the motor steering (from the fan end, turn counterclockwise) . The oil-fired boiler needs to check the safety valve once a year. Carry out a comprehensive overhaul and maintenance of the boiler.(121) Economic Analysis of Oil-fired Boiler heating
