Main features of coal fired steam boiler
Performance advantage
1. The steam boiler is the horizontal quick-loading boiler with natural circulation of working medium.
The boiler heat exchange system is composed of a boiler barrel, a set box and a water cooling wall. The main heating surface is composed of a furnace water cooling wall, part of the boiler barrel and a convection tube bundle inside the boiler barrel.
2. Advanced design performance:
The main heating surface tube of the boiler is made of seamless steel tube of no. 20 low and medium pressure boiler, and the boiler barrel is made of special steel plate for the boiler.The left and right containers are made of seamless steel tubes.
3. The boiler arch is made of fire-resistant concrete.The rear arch is low and long, so it burns well. The wings of the flue and the side wall tiles are made of refractory sintered bricks.Boiler front wall and back wall adopt universal firebrick.
4. Reasonable exhaust ventilation, large combustion chamber and strong applicability of coal.Suitable for all kinds of bituminous coal or anthracite, mixed coal.Well burned.Because the high-temperature flue gas first enters the settlement chamber, and then from both sides enters the two wings of the flue and the front smoke box, so the effect of smoke removal and dust removal is good.
5. Simple water circulation, reasonable structure of pressurized parts, and safe operation under the condition of ensuring water quality.
6. The combustion equipment is a fast-loading grate, which can be manufactured and installed in the factory and directly installed on the foundation after being transported to the site.With reasonable structure, compact, low steel consumption, so that the boiler performance, weight, structure and size compared with domestic products with the same capacity has obvious advanced.
7. Energy saving and environmental protection
biomass steam boiler adopt the latest gasification combustion technology, set up the advanced gasification rotary combustor, built-in cyclone secondary air distribution, make fuel combustion more full.
8, and the use of efficient heat transfer elements - threaded smoke pipe, with a reasonable flow of flue gas, so that the boiler thermal efficiency is higher.The thermal efficiency is over 85%.
9. The steam boiler adopts the green renewable biomass lignin pellet fuel promoted by the state, with zero CO2 emission, smoke emission concentration less than 50mg/m3, smoke blackness less than Ringerman I class, and all indicators meet the national environmental protection standards of the first class.
10. Low operating cost: The fuel lignin biomass pellet used by the boiler is a new type of environmental protection fuel supported and promoted by the state. It is a renewable resource.It has the characteristics of high calorific value, low cost and wide source.Its operating costs are only a quarter of those of electric boilers and less than half of those of oil-fired (gas-fired) steam boilers.
11, high degree of automation: digital integrated controller, according to the user can set the automatic controller burning conditions, simple and convenient operation, automatic ignition, automatic feeding, automatic ash cleaning, gas boiler operation is equally convenient.
Application for biomass steam boiler
Wood fired steam boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.
