2 ton boiler applied in paper mill
Third, the full absorption of flue gas waste heat
Boiler flue will continue to exclude a large number of high-temperature flue gas, which will be part of the flue gas heat away into the atmosphere, causing heat loss. Therefore, the high temperature flue gas heat recovery, is an effective energy-saving measures at boiler heating.
Gas-fired steam 2 ton boiler applied in paper mill: 20 tons of gas boiler gas consumption calculation method outlined gas boiler China is now the most common heating enterprises use boilers. Henan gas steam boiler many enterprises will choose the main heat boiler 20 t most gas boiler operation. The 20 tons of gas boiler gas consumption is how much? Gas boiler gas consumption and how to calculate it? There are a lot of users do not know how to calculate the gas consumption of the gas boiler at the time of purchase Pa Leishi boiler. Now, Palei Shi Xiao Bian tell you, the low calorific value gas boiler gas consumption depends on how much gas. For example, if natural gas heat value 8600kcal / Nm3, it produces steam 79Nm3 / ton. Of course, because of the different quality of natural gas supply regions, different quality gas boiler, mix the amount of air is different. So these numbers are all estimates out. A thermal efficiency of the gas boiler is 88% calculated, if the use of a high thermal efficiency of the boiler, then the gas boiler will be a corresponding decrease in gas consumption. Running costs of gas-fired boiler popular impact natural gas supply, local gas prices significantly affect the level of air consumption and operating costs of gas-fired boiler. The gas boiler thermal efficiency of its operation also determines the efficiency of natural gas use. US imports of Pa Leishi thermal efficiency gas boiler is 90%. The atmosphere is a premixed commercial cast iron boilers. Its strong thermal efficiency can effectively improve the efficiency of use of natural gas, in the same amount of natural gas use, Pa Leishi boilers can effectively reduce the air consumption of gas boilers, to reduce the use of natural gas to users, cost reduction effect.
Before coming heating season, Pinggu and Yanqing, Miyun three areas have been completed six large coal-fired 2 ton boiler applied in paper mill clean energy transformation, involving a total of 1660 tons of steam, residential heating area of about 900 square meters, in order to promote the city's urban focus heating basically clean heating to make a strong contribution.
It is reported that, in addition to this rural area south of the coal-fired boiler house for reasons of space, and the remaining five of the original coal-fired boiler room facility will be retained as an emergency backup. Pinggu District-Valley heating plant boiler clean energy transformation project has been debugging equipment, the boiler room of the original four coal-fired boilers, a total of 400 tons of steam, heating an area of about 2.5 million square meters, the new 3 sets of 100 tons of steam gas boiler is equipped with a heat pump.
Also, according to plan, City Management Committee led the development of the annual Yajian coal and clean energy facilities construction program to focus on the northern region, enhance power supply, gas supply capacity, promote Plains natural gas pipeline "town pass" to protect coal demand for clean energy. The basic realization of the city's plains village "No Coal", the phasing out of bulk coal sales within the region transformation of the industry and commerce department for bulk coal sales cancellation of registration in accordance with law, in principle, be issued a new business license. For failure to implement clean heating in winter 2018 and not included in the annual village "coal to clean energy" program, full implementation of quality coal instead.
Reduction of carbon dioxide, sulfur dioxide emissions
Pinggu District Management Committee, according to the person in charge, Riverside, Xia Xing Coal Valley and heating plant is heating an area of 7.416 million square meters, of which the heating plant heating Riverfront area of 4.1 million square meters, the Xingu heating plant heating an area of 2.808 million square meters, summer Coal heating plant heating area 508,000 square meters.
By upgrading "coal to gas", three heating plants meet emission standards Beijing local standard NOx emissions of less than 30 mg / standard cubic meter, while the amount of coal Yajian 160,000 tons per year, greatly reduce emissions of carbon dioxide, sulfur dioxide, nitrogen oxide.
Among them, Xingu heating plant "coal to gas" project officially started on May 16 this year, October 20, Sheung Shui, October 27 with the ignition conditions.
Riverside heating plant "coal to gas" on May 16 this year started, has completed the boiler and associated piping, heat pumps and ancillary equipment installation, ongoing electrical, control system debugging, October 22 has been Sheung Shui, October 29 have ignition conditions.
Summer Coal heating plant "coal gas" this year officially started on August 18, has completed commissioning of boiler facilities and associated piping, heat pumps and ancillary equipment installation, ongoing electrical, control systems, etc., on October 29 water, with firing conditions.
When the 2 ton boiler applied in paper mill to conduct regular sewage? why? 1, on a regular basis during boiler blowdown procedures Stokes provisions, when the pressure is increased to 0.3MPa, lower header to regular sewage water wall once. Its role is three: the first function is excluded in the second line box of precipitated impurities. The second effect is that the uniform temperature associated tank. Stokes waterwall process due to uneven heating, cycle rate waterwall tubes in each range, even some stagnant, which makes the entire second line different water tank, so that uneven thermal expansion of the header. Sewage regularly eliminates uneven heating, the circulation flow rate in the water wall tube is substantially equal to the same header. The third role is to check regularly outfall is smooth, if clogged sewage pipes, treated invalid, it is necessary shutdown process. 2, the initial ignition of boiler blowdown regularly at this time for regular sewage, discharge of water in the bottom part of the cycle, not only the impurities to be discharged, to ensure the pot of water quality, and the circulation loop heat exchanger to heat the weaker part of strengthened to prevent the local stagnant water cycle, so that each of the water system components uniformly expanded metal heating surface, reducing the temperature difference between upper and lower walls of the drum.
