75 ton CFB pressure fire tube boiler price

Fuel Flexibility: The most important advantage of the CFB boiler is the flexibility of firing a wide range of coal from 9500 to 25000 kJ/kg. CFBs can also burn a limitless number of other types of solid fuels, separately or mixed with coal. The limitations if any are only in the feeding and other mechanical equipment. The output capacity and steam parameters depend on the heating value of the fuel.

75 ton CFB boiler can use different types of solid fuels that include low quality coal, lignites, coal blends, bagasse in sugar plants, bark in pulp and paper mills, coal washery rejects in mines, petcoke and other bio mass products. Most of these fuels are seasonal, production or availability dependent. Mixing with coal or using coal when other fuels are not available gives an uninterrupted steam and energy supply.

1. Sulphur Dioxide removal: Firing high Sulphur coal requires the use of a Flue Gas Desulphurisation (FGD) plant to keep emissions within statutory limits. An FGD is a complicated plant that requires high capital investment and operational cost. In a CFB limestone addition in the furnace converts the SO2 to sulphates during the combustion and circulation which goes out with the ash. A CFB boiler costs less than a PC fired boiler with an FGD.

2. NOx Reduction: The combustion temperature in the furnace in a CFB boiler is considerably less than PC boilers resulting in lower NOx emissions. There is no additional requirement of separate NOx capturing devices which reduces capital investment.

3. Maintenance: Eliminating the pulverizer and pulverized coal piping reduces maintenance, related outages and equipment redundancy. A part of this saving is offset by higher maintenance due to erosion in pressure parts and furnace area, and maintenance of the refractory.

Boiler installation of "blast doors," What is the role now on the market most of the pressure fire tube boiler prices to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door. Swing-proof doors are mostly placed in the furnace wall of the combustion chamber. Their installation position can be divided into vertical and tilting, by the door frame, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and to ensure seamless tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas in the furnace or flue explosion, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained. Most membrane blasting explosion vent means on the flue, and a clamping device consisting of explosive membrane. Bursting disc is typically made of a thin metal plate of asbestos, aluminum and stainless steel. When an explosion occurs in the furnace or flue gas generated shock wave pressure to bursting membrane damage, play the role of relief, once the explosion vent membrane after blasting effect, it will not reset itself, the clamping device must be open blasting repositioned membrane. Note 1, the position of general device explosion-proof door on the wall or on top of a steam boiler furnace furnace exit side of the furnace flue fuel gas. 2, explosion-proof doors should be installed in place without the threat of operator safety, and a pressure relief guide tube, it shall not be stored near inflammable and explosive materials, highly preferably not less than 2 meters. 3, activity blast doors require regular manual test to rust dead.

Shandong textile mill electric steam pressure fire tube boiler price how much the current price in many textile mills in Shandong region or to steam boilers for production of electricity. Because the local gas is not very adequate, resulting in a lot of companies do not have access natural gas, but is also required by environmental policy. So, for Shandong textile enterprises, the only use of electric steam boiler production. Recently, there is a textile enterprise in Shandong consult with fast boiler need to purchase an electric steam boilers for production, but for specific models and prices are not aware of. Boiler manufacturers need help accounting models and prices. In this regard, fast boiler according to the actual situation of the textile business accounting, concluded that the plant with electric steam boiler 2t is possible. Current procurement costs of around 20 million.
