What is the excess air coefficient of dealer boiler brand lithuania and boiler professionals work? Learning and understanding of the boiler, the following is mainly to answer some specific questions, which specifically is: What is the excess air ratio boiler? Its smoke is calculated, and what about? And, What are two boilers, not within the scope of supervisory inspection? Designed boiler work, which refers to what? What are the contents of their work? So, the next immediately to give a specific answer. 1. What is the excess air ratio boiler? Its smoke is calculated, and what about? Boiler excess air ratio, for the noun words, simply, is a boiler operation, the ratio between the actual and theoretical air consumption air consumption. For different types of boilers, it is not the same. For example, oil and gas furnace is 1.1, and the fluidized bed boiler, it is 1.1 to 1.2. As for the calculation of flue gas boiler, mainly related to combustion equipment type and fuel type two.
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.
The advantages of steam dealer boiler brand lithuania: charred slag is a chain out of the grate back through the automatic transmission, sent the furnace interior cleaner. From the rear, the boiler flue gas through a pot of return pipe to move forward. Structure of the biomass is returned to the steam boiler two rear return tube smoke, dust is then separated into a dust collector, then the fan is discharged by the fan stack.
Heard so much about fast dealer boiler brand lithuania made a number of achievements in the areas of clean boiler, this time my unit and quick cooperation parties, give me your company's boiler unit is in line with the requirements of our team boiler, to achieve a clean, energy-saving, environmentally friendly way of heating . Moreover, your company for the Beijing authorities have provided more office cleaning boilers, a good reputation. So, we finally reached a cooperation. --customer feedback
