Subsequently, the Secretary-General Wang Jiao Ling line with the company's quality control staff had a discussion on the case of the reform of administrative licensing review of the existing 2 ton boiler belarus model in the country, how to promote the development of high quality assessment boiler, with the assessment of how businesses, trade associations and work promoting industry innovation and innovation to lead the development of what the expectations and demands, boiler regulations and technical specifications and implementation issues recommendations related issues exist in the process conducted in-depth exchanges and discussions, and Lu, president of the company's quality management staff made a lot of valuable Suggest. Wang Jiao Ling Secretary-General spoke highly of the technical aspects of the advantages of fast Boiler green energy and green development, and other fast-outstanding contributions boiler industry group to promote environmental protection and efficient process affirmed.
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 power plant in Bulgaria consists of 11 2 ton boiler belaruss sized 160 and 220 t/h, fired with natural gas and coal. In order to meet the changing emission regulations and to reduce the fuel cost the customer was interested in replacement of 2 existing 220 t/h gas-fired boilers with a new CFB boiler fired with petcoke and Ukrainian semi -anthracite. Gas boilers no 7 and 8 were demolished, this space was used for a new CFB boiler plant .
Coal to natural gas operations bunch of factors that vertical pressure steam 2 ton boiler belarus energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.
