8 ton horizontal coal fired steam boiler for sale
Small electric 8 ton horizontal coal fired steam boiler for sales What are the benefits, features? First, electric and coal, oil steam generating comparative advantages and disadvantages: advantages and disadvantages of coal: Advantages: coal is the most economical energy per kilogram of coal can produce more than 5,000 calories, can produce about 6 kg steam (theoretical value). Both economical than electric, fuel oil and natural gas. Disadvantages: 1, low efficiency, although theoretically per kilogram of coal can produce more than 5,000 calories, but due to the limitations of coal-fired boilers and human factors affected the Boilermakers, the real heat of the steam is converted to produce much smaller than the theoretical value, the heat utilization rate of around 60%. 2, can not do automatic control, if the device is not continuous steady steam steam that instant steam consumption fluctuations, the steam produced by the boiler with the steam in the bottom of the valley steam equipment can only let go waste. 3, need specialized operators, high labor costs. 4, do not meet the requirements of modern environmental protection, to ban small coal-fired boilers is the trend. The advantages and disadvantages of fuel: fuel meets the requirements of environmental protection, the state has not been expressly provided, however, based on current oil prices, its economy has ceased to exist. Per liter of oil can produce more than 18,000 calories, about 60% utilization, we can produce about 10 kg of steam. Which produce one ton of steam costs around 800 dollars (at current prices). The advantages and disadvantages of heating: Cons: Because electricity is converted from the other sources of energy, so the relatively high price point, once electricity can produce about 1.5 kg of steam. Calculated to produce 1 ton of steam costs about 400 yuan or so based on the current average domestic electricity bill. More expensive than coal.
The characteristics of internal circulating fluidized bed boiler
The internal circulating fluidized bed boiler (ICFB) efficiently co-combusts industrial waste, biomass fuel and coal, provides steam or hot water, and sets new standards in limiting SOx and NOx generation. In addition to the characteristics of general CFB boiler, the internal CFB boiler also has the following special structure and characteristics:
1. The internal CFB boiler has buried pipes, which can increase the heating area and regulate the temperature in the dense area.
2. The internal CFB boiler has a large area of air distribution bed, so that the boiler has more heat storage, which is conducive to fuel combustion and burnout, and provides a congenital condition for a wider variety of coal adaptability;
3. The internal CFB boiler has a large cross-sectional area of the furnace, the flow rate of flue gas is low, which can improve the primary combustion rate of fuel, reduce the wear of the furnace, reduce the power consumption and energy consumption;
4. The wind arch composed of secondary air can supply oxygen and disturbance on the one hand, and on the other hand, can lengthen the combustion time of coal, which is conducive to coal burnout;
5. Water-cooled membrane wall of the cyclone separator, effectively prevent high temperature coking and center cylinder bias, which improves the efficiency of the separator;
6. Porous and controllable feed return valve makes the feed return reliable, even if the feed return has a coke block, since there are a lot of feed back port, there is no need to immediately stop the furnace, the user can stop the furnace when it is available for them to clear the coke.
7. Tail flue gas duct patented technology: water cooling furnace roof and chevron water cooling flue gas duct, can effectively solve the roof and smoke wall collapse and leakage of ash or air, which improve the environment of the boiler room.
Small 8 ton horizontal coal fired steam boiler for sales will be fully modernized popular in the market after the 1980s, China's economy has undergone rapid changes in boiler industry is more prominent, national boiler manufacturing companies increased by nearly 1/2, small steam boilers will be fully prevalent in the modern market, and It can be formed independent development of generation after generation of new products. Small steam boiler is the era of economic development indispensable commodity, what the future will bring, but is well worth study. Group mainly used for small industrial R & D and production of small steam boiler, as far as we know, much higher production of small steam boiler manufacturers of small steam boiler prices, leading to small industrial input costs are also high, so many customers stay away, we had to continue small traditional steam boilers. Small steam boilers will be fully popular us on this cost, has been doing research experiments, and finally developed a small steam boilers for small industrial production process used at the beginning of 2017, we produced a small overall structure of the steam boiler Unlike other steam boilers in the modern market , through our special processing technology, the structure of the entire boiler changes, the use of safer, lower operating costs, more cost savings for small industry owners. Small steam boilers will be fully prevalent in the modern market, the Group's how we analyze the energy industry Riding out the following four points:? First, in terms of environmental protection, small steam boiler burning material is primarily natural gas, natural gas is a now clean energy, without waste combustion, the exhaust gases, as compared to coal, oil and other energy sources have a safe, high calorific value, clean and other advantages. Small steam boilers will be fully prevalent in the modern market two small steam boiler from a safety point of view is generally aspirated pipeline, the use of gas pressure units pre-tuned, fuel combustion more fully, the boiler is stable. Third, the thermal efficiency perspective, a small part of a steam boiler steam boiler pressure, since the connection within the furnace condensing system, the exhaust gas temperature is less than 110 deg.] C, operating thermal efficiency of 93%. Fourth, the use of the economic point of view, since the small water capacity of less than 30 liters steam boiler, from cold start to 5 minutes to produce saturated steam, warm-up time is greatly reduced, saving energy. Automatic intelligent operation, no fireman guard, eliminating salary expenses. Small steam boilers will be fully prevalent in the modern market is not difficult to see that the future prospects for the development of small steam boiler is very broad, because it is a vertical, small, small footprint, easy installation, small steam boiler to replace the traditional small excellent product steam boiler.
Dongguan City, Guangdong Province in phasing out coal-fired boilers to replace the environmental transformation, biomass boilers in industries packaging, leather, clothing, textile and other widely used. However, biomass boilers still present drawbacks: If insufficient biomass combustion, typically generate a lot of dust, nitrogen oxides and other pollutants, improving PM2.5 concentration, air quality.
Dongguan City Atmospheric Office official said that since the Dongguan started Blue Sky Battle since, the city ton output capacity the courage to decisively eliminate those high pollution and high emissions industries and enterprises, won the majority of the masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity. In the eco-friendly background, out of high pollution equipment is the trend.
Transformation and upgrading of enterprises demand, government support policies have, inside and outside the echo, Dongguan out of biomass boilers into the fast lane. As of January 10, a biomass boiler out of the task of the city within 31 town street in Shilong, South City, the nave, Ma Yong, Hou Jie, stream, Feng Gang, Xie Gang, Chang Ping, Shek Pai, Chashan 11 Towns in the completion of the task of eliminating all living matter within the jurisdiction of the boiler. In addition, Long, Qi Shi, Tangxia, Sha Tin Kau five towns out of the completion of more than 90%, the remaining 15 Towns also have the confidence out of the task in the year 2019.
While out of the biomass boiler, Dongguan City, accelerate the pace of construction of gas pipeline to provide clean energy for the needs of the enterprise.
Atmospheric Office official admits:. "A few years ago, the city lags behind the construction of the gas pipeline, laying of pipe network coverage area of a small number of enterprises in the coal phase-out of high-polluting fuels, the use of biomass boilers as an interim energy supply equipment, there are also often allowed to change the fuel business, steal burning coal. "but now, due to the environmental protection departments to actively coordinate the town street, village (community), industrial areas, and vigorously promote the construction of natural gas pipeline, starting from the source to provide clean energy for businesses, stealing burn the behavior of coal is greatly reduced.
Over the past year, the city has a new natural gas pipeline 256.6 kilometers, 530 companies have security using natural gas. The city urban management department based on the actual distribution of useful gas needs of enterprises to develop business for the city's more than 600 natural gas pipeline construction plan and coordinate the new Austrian, Xinghua, often positive and three gas pipeline company to carry out construction work to ensure that the natural gas pipeline construction project smoothly, so that more companies access to clean energy as soon as possible.
According to statistics, date, Dongguan City gas pipeline or central heating station accessible area of 660 biomass boilers, has eliminated 572 units, 41 enterprises have to apply for the boiler out of subsidies.
