szl coal fired water tube boiler

Steam szl coal fired water tube boiler When should an emergency shutdown when the steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.

When fully completed by the end of 2017 urban 10 tons of steam / 10-20 tons of steam szl coal fired water tube boiler regulation task and gas pipeline network coverage of the coal / coal-fired boiler renovation work, fully completed before the end of 2018, 20 tons of steam urban / when more than 35 tons of steam / h coal-fired boilers and renovation work. Before the end of 2017, high-pollution fuel combustion zone ban all types of urban areas in high-pollution fuel boiler to stop using all, or switching to natural gas, liquefied petroleum gas, electricity and other clean energy.

To help businesses to reduce costs to switch to clean energy, the program presents a series of supporting policies and measures, establish clear criteria subsidies, subsidies for the 2017,2018 two years time.

Vertical steam szl coal fired water tube boiler introduce vertical steam boiler Products: vertical steam boiler, all kinds of domestic furnaces comprehensive technical improvements, absorb the international advanced technology and the introduction of the new generation of horizontal fuel (gas) boilers, the product has been designed applied for the patent, the boiler head boiler shell, boiler shell, U-rings, furnace, furnace head, transverse pipes, tubes cupola. Combustion boiler using conventional techniques, from the media into the door hole, in the upper combustion grate, the flue gas was washed repeatedly laterally staggered in the cross-pipe furnace, in the flue gas containing fine dust particles and carbon black during the rise , multilayered tube is blocked, reducing the speed of movement, again falls on the combustion grate, burn the fumes into the atmosphere through the chimney. Performance: the boiler furnace grate rests within an upper portion of the U-shaped scraps, the direct flame furnace, and flushing mounted within curved tube furnace; vertical bent tube boiler structural features are: furnace interior curved inner pipe, increase radiation heating area. However, due to large water-cooling degree furnace, the furnace temperature reduced accordingly, therefore, generally suitable for burning high quality coal. The increase in the furnace masonry bricks, to maintain a high temperature furnace burn less coal. Better water circulation, where the site has been washed flue gas cooling water, the whole structure, good elasticity. Features: use of double grate combustion section of the combustion chamber, heating up, fast boosting of unburnt gas through the secondary combustion, functions as combustion, smoke, dust effect. Bending the upper furnace tube arrangement convection heating region, disposed in the lower furnace grate tubes and radiation heating furnace area, structure of the furnace and the flue gas flow, reasonable layout, good heat transfer, the boiler reasonable design, simple structure operation, easy maintenance, small footprint, less investment in infrastructure, the company is one of small enterprises with steam, heating and other equipment ideal.

Use the hotel szl coal fired water tube boiler should pay attention to what the weather is cold, the hotel is primarily a boiler to heat up water to provide hot water to the guests. As the state environmental requirements higher and higher, people continue to improve the boiler, boiler making to become more resource conservation and energy savings, and some boiler operation is very convenient, high combustion efficiency. With the increasing emphasis on environmental protection in the country, as well as the stringent requirements of energy conservation in recent years, basically around the large chimney have been demolished, and many hotels Bath boiler manufacturers have their own specialized products for the upgrading and the development and transformation of environmental technology. Many environmentalists boiler manufacturers have been committed to the exploration and development of gas boiler industry. There is a number of R & D of fuel gas-fired boilers, which are also more mature now, some of the techniques. Especially for hotel bath boiler of this series of products, as this not only applies to a series of boiler and simple hotel bath center, it is also widely used in daily residential water supply, power plants and other steam boiler unit supporting the use of , so for some of these products to develop innovative energy saving technologies listed hotel bath boiler, will directly affect the overall trend of China's environmental protection boiler market. Take the fuel gas furnace, it is one of the energy saving aspects of the world's most sophisticated technology so far. On the one hand fuel gas-fired boiler can achieve full automatic control, intelligent automation, and the use of non-polluting, high combustion efficiency. Gas boiler due to the low efficiency of coal combustion, the process will discharge a lot of harmful gases such as carbon monoxide, sulfur dioxide, nitrogen oxides, etc., and accompanied by a lot of smoke, air pollution. Different gas boiler, gas boiler because of its specificity resulting in combustion of the fuel product is predominantly water and carbon dioxide, low air pollution, energy conservation comply with national requirements, and high thermal efficiency. From the current development situation, whether it is a hotel bath boiler or a variety of industrial boilers, energy saving and environmental protection go route, is unique selection, the difference lies in the stability of the maturity of the technology, as well as environmental protection boiler manufacturers in the technology and research efforts on investment, the future of the industry who can lead boiler environmental protection boiler market will be able to occupy the leading position in the industry.
