dzl fire tuble coal fired steam boiler china

What are the methods to reduce pollution mill 1, check for leakage protection and maintenance of: 2 mm steam leakage will cause energy losses of more than 10 tons of coal each year do? When you do not use it, you can turn it off to save energy. For water, steam and compressed air leak survey and routine maintenance, cost very little. 2, the non-contact cooling water in repeated use: Since the non-contact cooling water temperature and the quality is very good, it can be reused for desizing, scouring, rinsing and other processes. Three best source of cooling water is regenerated: sintering machine, a pre-link and compressor systems. The plant water recovery system may be installed, pipes, valves, storage tanks, and control systems. 3, repeated use of steam condensate: Textile mills require large amounts of saturated water vapor in the dyeing process, wherein a portion of the condensate is converted to its high temperature and purity. Water can be pumped back to the boiler to form a new steam. For those who buy steam from suppliers, or boiler is located away from the dyeing process, the condensate can be used as water washing or desizing. 4, pre-treated wastewater reuse Procedure collected bleaching, mercerizing machine, the water can be reused in other programs, there is no direct discharge of wastewater. 5, hot wash water is recovered from the hot gas in the dyeing process, large amounts of hot water are used to wash. Heat the washing water can be collected by the system plate heat exchanger to preheat the water to be sent to the next washing. 6, pre-screened coal enterprises should introduce screening spiral coal boiler technology to selection of raw materials. It is possible to improve the media tell the good, the bad quality of proportion, to avoid loss of small volumes of coal and coal calorific value. 7, maintaining steam traps traps can help maintain effective delivery of the steam plant. The valve is removed from the steam pipe and prevent further condensation water, so as to avoid heat loss and reduce fuel consumption. 8, the piping, valves and heat insulated flange experience pipes, valves and flanges waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery from the boiler chimney at a temperature of 360 ℃ smoking, sometimes discharged directly into the atmosphere, there is no heat recovery. In fact, this heat can be used to preheat boiler water, steam or create a new steam system. 10, optimization of compressed air systems consume a large amount of compressed air in many parts of textile machines Mills. These instruments are prone to leakage, particularly in a threaded joint, rubber joints, valves, automatic regulator, the inflatable device and the old gasket. In addition, the use of compressed air pressure is usually based on the maximum pressure setting; reduce this pressure is feasible and would not have any negative impact manufacturing.

Washing plant choose what fuel dzl fire tuble coal fired steam boiler china more cost effective? Washing plant with a steam boiler fuel is more cost effective to what has been plagued by the problem that a lot of users, and today we analyze this problem. According to cost savings for the selection of coal-fired or biomass steam boiler more cost effective, gas steam boiler is relatively easy but the cost is relatively high, in some places not to use coal and no natural gas pipeline, then select the burn methanol, more than liquefied petroleum gas and fuel oil province, Taikang County Hengyu thermal equipment Co., Ltd. is specialized in producing supervisory inspection-free steam boiler, a more comprehensive model specifications from 0.3 tons to 0.5 tons of large tonnage steam boilers, coal-fired fuel, raw materials, fuel gas and combustion of methanol, fully automatic operation out of steam quickly and does not require supervisory inspection, I have a lot of cases washing plant, the company Sina, Netease, Tencent and other major news HC have reported. What you do not understand can inquire our company.

6 tons gas dzl fire tuble coal fired steam boiler china steam pressure adjusting a boiler operation, must frequently monitor the pressure gauge indicated. To maintain stable steam pressure, boiler pressure must not exceed the design pressure. Second, increasing boiler load: Steam pressure decreased boiler load is increased, if the level is high at this time, the amount of water should be reduced to a water supply or suspend, the amount of coal and increase the air volume. Gradually increase the amount of water at the same time to strengthen the burning, keep the steam pressure and the water level is normal. Third, the boiler load reduction: the vapor pressure rises to reduce boiler load, if the level is high at this time, the amount of coal should be reduced and the air volume, reduced combustion. Then the appropriate water reduction or suspension of water supply to the water vapor pressure and stability in the nominal range. Then press the normal combustion and the amount of feed water 8 to adjust. If the actual water level within the boiler is low, to increase the amount of water should, until the water level returns to normal after the combustion and needs to be adjusted according to the water vapor pressure and load changes.

It is reported that in the phase-out of coal-fired boiler reconstruction project, Jinan City, Shandong Province Finance Bureau has appropriated out of the transformation of coal-fired boilers municipal county area of ​​awards and subsidies 310 million yuan for the enterprises, units out of coal-fired boilers and special awards subsidy.

The allocation of financial awards complement funds, aims to accelerate the transformation of the city's coal-fired boilers out of work, to further improve air quality, according to the municipal government office "on accelerating the transformation of the city's coal-fired boilers out of work notice" (Ji Zheng Ban word [2017] 4) the requirements of the embodiment.

According to the municipal environmental protection department statistics, in 2017 the transformation range Jinan included in the elimination of 35 tons of steam and the following business units of coal-fired boilers 323 units, 1605 tons of steam coal-fired boiler units of 69, 189 tons of steam; the need for ultra-low emissions the transformation of more than 35 tons of steam coal-fired boilers of 94, 14 960 tons of steam. The issued rewards and subsidies, the Municipal Finance Bureau to take "the first disbursement, after the liquidation," the way out of the transformation of the inclusion of ultra-low emissions and transform the scope of coal-fired boilers in 2017 the implementation of full coverage, in accordance with the award criteria make a one-time pre dial counties and districts, counties and districts in the implementation of rehabilitation programs out of the boiler can award up early disbursement of funds of enterprises and units, to be enterprise, unit after the completion of the transformation carried out of funds liquidation.

Meanwhile, the Municipal Finance Bureau called on counties and district financial departments should closely cooperate with the environmental protection department, the main responsibility for the effective implementation of good out of the transformation of coal-fired boilers, will award up funds earmarked for municipal 35 tons of steam coal-fired boilers and substitution and elimination more than 35 tons of steam coal-fired boiler reconstruction project of ultra-low emissions (including troops out of coal-fired boiler replacement) cash incentives and subsidies, strengthen capital management, give full play to the financial capital efficiency.
