dzl steam coal industrial boiler

Mill steam dzl steam coal industrial boilers to reduce pollution which method 1, leak checking and maintenance of protection: 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, reuse 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, pipe insulation pipes, valves and flanges, valves and flanges experience hot waste of resources, reducing efficiency. Steam delivery device insulated to prevent vapor loss is an inexpensive, energy-saving method of .9, the heat recovery boiler chimney smoke at a temperature of 360 deg.] C, and sometimes directly discharged 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.

6 tons gas steam dzl steam coal industrial boiler 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.

Several factors underlie the vertical steam dzl steam coal industrial boiler efficiency China has been working to catch on coal to natural gas, vertical steam boiler with greatly reduced contamination of dust, smoke and other effects of a nitric oxide gas has also been healthy curb. Efficiency is an important indicator of a measure of vertical steam boiler, a good number of factors under the topic to discuss the direct impact of vertical steam boiler efficiency began. After analysis of stakeholders, heat loss from vertical steam boiler contains two pieces: the proportion of full combustion air with flue gas emissions unreasonable heat loss. Heat loss can be reduced smoke emission can be installed at the end of the vertical steam boiler stack waste heat reuse install, or more leading system with condensing boiler. Combustion air ratio sufficient unreasonable faults into: general vertical ejector-type steam boiler burner selection, resulting in a motor fuel ratio can not be adjusted. Most of the selected vertical steam boiler is mechanically strong emission combustion engine, air-fuel ratio resulting irrational factors are the following: air-fuel ratio can be divided into two reasonable chance comprising: when the air in excess, the excess will have full cold It is heated, resulting in increased operating costs vertical steam boiler, steam boiler efficiency vertical drop; when the air is not enough, will produce insufficient burning phenomenon, caused by vertical steam boiler efficiency.

Recently, the Guangzhou City issued an action "Guangzhou 2018 annual work plan for comprehensive prevention and control of air pollution," the bureau of law enforcement to monitor the detachment on August 28 = 29 organizations launched a special enforcement action against a biomass dzl steam coal industrial boiler.

The special enforcement action by the municipal and district levels of environmental protection departments jointly launched, deployed Yuexiu, Tianhe, Haizhu, Huangpu, Conghua five district environmental protection law enforcement backbone, with the Guangzhou City Environmental Protection law enforcement inspection detachment composed of 18 cross-law enforcement group, to increase the city all registration to carry out quality checks of 125 biomass boilers in the book, focus on examination of Guangzhou boiler emissions monitoring system in Zengcheng District registered the existence of complex biomass boilers coal or other high-polluting fuels, whether there are special furnace and supporting bag dust removal facilities, whether the normal operation of the boiler control facilities, whether discharge standards as required entry and update Guangzhou boiler emission monitoring system and other issues.

After verification, the registration system by the city list in the boiler has been disabled (off or relocated) boiler station 43, not included in the other eight found regulatory list table 133 actually inspected. Among them, 28 units involving suspected violations accounted for in the boiler problem with the boiler (90 units) ratio of 31%, the problem of coal-fired boilers in complex 2, the resurgence of firewood, 11, allegedly did not apply for environmental protection procedures, waste gas treatment is not installed facility or facilities are not the normal use and other illegal activities 15. For complex high-polluting coal and wood fuel boiler according to law-site seizure and transfer penalties and territorial environmental protection departments to follow up treatment in accordance with the relevant provisions of Article 107 of the "People's Republic of China Air Pollution Prevention Law." The rest were arrested for illegal transfer of territorial environmental protection departments for investigation.
