10ton coal fired 25bar steam boiler
Gas-fired 10ton coal fired 25bar steam boiler and gas steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas steam boiler and gas steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answer the same model as compared to steam boilers or gas steam boiler energy conservation, we can roughly be calculated next-ton per hour boiler full load of work to 150-160Kg coal according to the market value of fuel gas and gas to about 80m3 . A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.
Mature technology in biomass boiler, our SZL series chain grate boiler widely available renewable energy technology that generate steam from 6 to 40 ton to any industry factories, facilities, plants, etc. What’s more, our ZG Boiler can can supply larger capacity and high pressure circulating fluided bed, power plant boiler, biomass boiler, produce steam for electricity or other requirements. A fully automated operation system, similar to those used for conveying feed and grain on farms, delivers biomass pellets from an outdoor silo to the boiler’s hopper. At a rate predetermined by user-controlled settings, a fuel-feed system then delivers the pellets to a combustion chamber. Pellets are burned using staged combustion air injection (a process that reduces NOx ). A cyclone separator knocks out particulate matter that is then removed by an on-line, automated mechanical cleaning and ashremoval system. Usually, biomass fired cfb boiler has higher thermal transferring efficiency than chain grate boiler. And both of them can burn mixed fuels like wood pellet and coal; bagasses and coal; palm shell and coal etc.
Stanley Agricultural Group Co., Ltd. is specialized in the production and sale of fertilizer and other agricultural technology promotion of integrated services provider, has total assets of 6.3 billion yuan, more than 8,000 employees, annual production capacity of 5.2 million tons. Earlier this year, fast Boiler stand out in many boiler brand competition, and Stanley reached a cooperation, to provide a whole 10 tons of steam condensing 10ton coal fired 25bar steam boiler (WNS10-1.25-Y.Q), provide support for the heat Stanley fertilizer plant.
6 tons adjusting a combustion gas 10ton coal fired 25bar steam boiler, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.
