ZG is continuously working on further improving the already very high efficiency and co-combustion capability of its circulating fluidized bed cfbc boiler project final year mechanical engineerings.Efficiency increase and co-firing of coal with CO2 neutral fuels provide a technically and economically feasible solution to the CO2 issue in the short and medium term,while major emission cuts possibly required in the future call for more powerful solutions.
Furnace excess air ratio control is an important indicator of gas cfbc boiler project final year mechanical engineering furnace combustion process. For Stoker, requires excess air ratio at the outlet of the furnace is generally between 1.3-1.5, the amount of flue gas flowing leakage calculation for each section of the flue, exhaust excess air ratio should be at 1.8 to 2.0.
Why cfbc boiler project final year mechanical engineering always pay? Phenomenon: the pressure gauge shows the value of frequent falling, falling. Normal water pressure of the boiler must be greater than 0.8bar, replenishment cycle in 3-6 months or more. The boiler is connected to the cooling system in the room together to form the heating system. Pressure gauge is displayed on the boiler pressure value of the entire heating system, so that the replenishment is the replenishment of the entire heating system. Therefore, in most cases often pay a heating system problems that may arise, not the problem of the boiler. One reason: in the pre-commissioning of the new system heating system commissioning new air heating system more automatic exhaust valve release system results in reduced pressure, requiring multiple replenishment. Two reasons: heating system for leaks out pipe heating system or ground heat sealing leakage may occur at the interface and the leaks little leakage, since the heating boiler is in the state of the whole system is hot, so the leakage the rapid evaporation of the water is difficult to find the leak by the naked eye. If the pressure off the boiler and can not appear to find the leak, we recommend that you check the boiler leaks. Inspection method: After stopping the boiler operation, close the bottom of the heating boiler supply and return valves (the valve can ensure shutting), disconnected from the system directly to the boiler, the boiler supply water to an integer value, a period of observation to see if there are fluctuations in pressure gauge . This method may be simply determined to be a problem after the boiler or heating system piping valve leakage problem. Reason Three: The expansion tank expansion tank failures would result in failure of the boiler heating system pressure exceeds 3bar the boiler drain valve protection. Contact your dealer for a replacement. Four reasons: replenishment valve closed lax if replenishment valve closed lax and low pressure water pipe network, the system will fall in pressure when using hot water. Solution: If frequent replenishment of the situation, need to contact the service provider, check the heating system as soon as possible to avoid long-term damage to the boiler caused by replenishment.
Recently, Yuhang District, Hangzhou, Zhejiang Province, a printing company 20 steam tons / hour of coal-fired cfbc boiler project final year mechanical engineerings have been stalled, this is the last Yuhang district an industrial coal-fired boilers, which marks the shutting down of Yuhang District of industrial enterprises to bid farewell to coal energy structure of coal turned to natural gas and other clean energy, Yuhang District from entering the industrial coal-free era.
Yuhang District "coal-free zone" construction of road resistance and long. As a major industrial zone, a long time, Yuhang District to focus on coal-fired thermal power plants, coal-fired boilers and other industrial enterprises formed a coal-dominated energy consumption structure. In 2014, the maximum amount of coal Yuhang District reached 783,600 tons. Large coal consumption that emissions of sulfur dioxide, dust and the like remain high for many years.
In order to further deepen the air pollution control, to win the Battle of the blue sky, Yuhang District, from 2017, will gradually tangqi thermoelectric, thermoelectric and sea Chongxian three coal-fired thermoelectric power plant with all closed down, the sea of clean natural gas for thermoelectric realized heat. 3 thermal power plant shut down so that the region's coal consumption, pollutant emissions and other indicators to achieve substantial reductions in road construction of "coal-free zone" has taken a crucial step.
Yuhang bid farewell to coal road this did not stop. While coal-fired thermoelectric accounted for the bulk of coal consumption and pollution emissions, but only out of coal-fired power plant is not enough. 2018, the government decided to promote taking advantage of Yuhang District, the region within the remaining four coal-fired industrial enterprises (Coal Products) pot (kiln) furnace closed down or eliminated or modified.
Yuhang District to increase the proportion of electricity consumption, and actively guide the region's energy unit of coal to electricity, oil to electricity, gas bottle to electricity, the construction of an orderly distribution grid, promoting smart grid construction; continue to improve the level of utilization of natural gas, and urban area in addition to all the town cormorant birds, Baizhang full realization of natural gas supply, a total of 850 kilometers of natural gas pipeline construction and municipal gas transformation 45000; to promote the application of photovoltaic power generation, the region's industrial and commercial enterprises amounted to 173 megawatts of photovoltaic capacity building distributed, clean energy applications has taken shape in Yuhang District.
According to statistics, "Thirteen Five Year Plan" (2016-2020) since the implementation of environmental statistics included in Yuhang district industrial enterprises coal consumption from 588,900 tons in 2016 down to 38,900 tons in 2018, to drop in early 2019 0.
A substantial decline in coal consumption is brought to slash emissions of pollutants and air quality improved significantly. 2018, the main pollutant urban air Linping PM2.5 average concentration of 38 micrograms / cubic meter, decreased 40% in 2015. Region sulfur dioxide emissions of 7,833 tons in 2014 to 2018 had dropped more than 90%; NOx emissions to 8490 tons in 2014 to 2018 had dropped more than 60%.
