Liquid Propane Coal Steam Boiler
In mid-November, Langfang City, Hebei Province continue to promote coal-fired boiler pollution problem, do the atmospheric release 2018 Fourth supervision order, supervision order states: the country, relevant departments directly under the city's control to quickly take a series of measures to prevent and strictly control burning coal boiler pollution problems.
Now is the time winter heating season, but also the critical period of the comprehensive management of air pollution in the autumn and winter season, the coal-fired heating boiler emissions standards are the focus of Langfang City, air pollution prevention and control. To ensure that coal-fired heating to achieve effective control, reduce emissions, minimize the adverse effects on air quality, atmospheric Langfang City Office will join together to focus, determined to win the battle in autumn and winter air pollution of coal-fired boilers.
Steering proposed order, the relevant departments to combine their job requirements for environmental protection, to develop a coal-fired boiler heating energy saving solutions for special work, establish special supervision and inspection mechanism for all heating stations in the main city within the city limits, supervision and guidance heat stand while ensuring a stable discharge standards, to protect people spend a warm winter. Various environmental protection departments will strengthen the tracking and monitoring of emissions of various heating stations, to be serious penalties for excessive emissions of coal-fired boilers, but also will continue to maintain compliance or below the City heating boilers requirements set emission standards for reward and subsidies .
The transformation of low nitrogen boiler should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.
Mill liquid propane coal steam 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.

Coal fired boiler design features:
1.By adopting of double wings gas ducts, the fuel gas can go into the front gas tank easily, so the temperature of different front plates can be same. In this way, it can avoid the crackles happening in the plates.
2.Spiral tubes are installed in the drums, which can strengthen the heating transferring efficiency, at the same time, spiral tubes have the ability of dust removal, which can avoid the dust stratification in the tubes.
3.Both of the front and the back arches of the 10t/h series coal fired boiler design adopt mason work of water cool tubes wall structure, which can form permanent arches.
4.Separate adjustable wind chambers. Wind is feed from two sides. It adopts new type crank screw wind adjustment structure, so that the wind adjustment and ventilation cross section proportion is 100%, which can ensure the easy wind adjustment and make it symmetrically.
5.There is push-pull damper dust removal equipment. The damper adopt finish machining cast iron seal structure, thus the secondary combustion distortion and air leaking in the grate is effectively prevented.
