Favorable Factory Price 94 Heating Efficiency Vertical Steam Generator
China is the large number of small coal fired boilers, this part of the boiler unit is particularly suitable for the use of straw fuel fired , there are several reasons:
1.Biomass own characteristics, such as low density, to collect raw material, transport and storage has brought great difficulties, according to the level of tariffs in different regions, the general raw material transport over 50 km or more, its economic competitiveness will be substantially reduced, even though they have adopted the compression molding technique .
2.China's current majority of small coal-fired units desulfurization equipment is not installed, this part of the unit coal consumption is not only large, but also the level of SO2 and dust emissions are also much higher than the fire power units, even superior environmental performance of circulating fluidized bed boiler units, because of cost considerations, most of the circulating fluidized bed boiler unit of limestone system is not put into operation. Therefore, the use of existing small units burning low sulfur, low ash biomass fuels, substitution of coal, coal used for savings and efficient, the installation of desulphurization equipment fire power units, which alleviate pressure on the environment is very beneficial .
3.More importantly, the circulating fluidized bed boiler fuel for its wide adaptability, fuel for co-firing biomass basic need to make any changes, but also to bring the combustion efficiency, reduce emissions and slow down wear a wide range of benefits. This may make small generator / heating circulating fluidized bed boiler unit occupies an important position in the future utilization of biomass resources.
Since this year, Qingyang City, Gansu Province Environmental Protection Bureau to continue to improve air quality at the core, in order to implement the Air Pollution Control Act as the main line, adhere to the rule by the people, source control, increase the comprehensive management of air pollution, construction of accurate and efficient and fine air pollution comprehensive prevention and control system, to fight air pollution control tough fight.
Qingyang Xifeng Kowloon City Road, South Street neighborhood community coal-fired boilers in accordance with the "clear" work requirements, continue to increase coal-fired boilers "cleared" efforts, multi-pronged, comprehensive treatment of the families of Xifeng Animal Husbandry Bureau building coal-fired boilers were removed.
Since coal-fired boilers to carry out "clear" its work, Kowloon South attaches great importance to the community, seven coal-fired boilers within the jurisdiction of actively deployed, timely follow-up, held a special arrangement will, continue to strengthen measures. In the community workers and urged many times to persuade, the District Animal Husbandry Bureau family member courtyard boiler successfully removed. After removal of this coal-fired boilers, coal-fired boiler demolition community task has been completed.
Phase out coal-fired boilers is an important measure to improve the air quality of the environment, but also the strong expectations of the masses. The demolition action, and effectively promote the area to carry out "the image of the city, the level of management" to work for the creation of a national civilized city to make its due contribution.
Vietnam Biomass CFB boiler in Sugarcan Mill Technology
The prime technology for sugar mill cogeneration is the conventional steam-Rankine cycle design for conversion of fuel into electricity.A combination of stored and fresh bagasse is usually fed to a specially designed furnace to generate steam in a boiler at typical pressures and temperatures of usually more than 40 bars and 440°C respectively.The high pressure steam is then expanded either in a back pressure or single extraction back pressure or single extraction condensing or double extraction cum condensing type turbo generator operating at similar inlet steam conditions.
Gas-fired boiler or electric boiler which is good?To compare the two kinds of boilers better, we need to understand the advantages and disadvantages of the boilers. The advantages of electric boiler are: 1, high thermal efficiency: can meet the requirements of winter heating in all regions; 2, electric boiler is beneficial to environmental protection: no leakage, low noise, no pollution; 3, convenient use: automatic control, no special guard; Intelligent thermostat automatic control, flexible and convenient use, indoor temperature can be set by their own needs, start and close the machine can be controlled by the computer. The disadvantages of electric boilers are: 1. The operation cost is high, is gas-fired boiler 2 times, is gas-fired boiler 4 times. 2. The boiler must be supplied with three-phase electricity at 380 volts. If there is a power loss or power outage, there is no alternative. Seriously affect the normal production and operation of enterprise units. The advantages of gas-fired boiler are as follows: (1) the thermal efficiency is as high as 90%: it can meet the requirements of hot water heating in all regions; 2. Gas-fired boilers are conducive to the national strategy of energy conservation and emission reduction, collect agricultural and forestry wastes such as straws that are directly burned and cause pollution, and produce gas granular fuels through processing, which can bring benefits to farmers. Greatly reduce emissions of pollutants from exhaust gases. 3, convenient use: full automatic control, no special guard; flexible and convenient use, 4, gas fuel is similar to coal gasification combustion and suspension combustion state, flue gas stays in the high temperature furnace for a long time, through the use of the gas fuel is similar to the coal gasification combustion and suspension combustion state. Multiple air distribution, anaerobic, upper feed, lower fire, lower suction combustion, full combustion, high fuel utilization rate, no black smoke. 5, using the furnace dust removal device, with which the original concentration of boiler dust emission is low, can not use chimneys. 6, continuous fuel combustion, stable operating conditions, do not be affected by the addition of fuel or stabbing, can ensure output. 7, the fuel source is extensive, the cost is low. Not limited by the season, can be used throughout the year. The gas-fired boiler is half of the gas-fired boiler, 1/3 of the oil-fired boiler and 1/4 of the electric boiler. 9. Fangkuai gas-fired boiler In a modular design, each system uses one furnace body, two combustion heads or two furnace heads, one burner head 300000 truck in summer, and two burner heads 600000 truck when heating in autumn. When the coldest in winter, you can open four burning stoves 80-1.8 million truck, that is, the heating boiler only uses 300000 calories in summer, 600000 calories in autumn, 1.8 million calories in winter, one machine multi-use. In this way, customers do not need to invest in two sets of equipment systems, greatly reducing their first investment costs and operating costs. The disadvantages of gas-fired boilers are: 1. Need free space or The warehouse is used for storing gas particle fuel; 2. Blower induced fan and other accessories need 220 volts, affected by power outages, but diesel engine can be used to power boiler accessories. Keep the boiler running as usual! Summary: gas-fired boilers and electric boilers are environment-friendly boilers, automatic control, can adapt to various areas, the price of raw materials is stable; but the operating costs of electric boilers are too high to be affordable by ordinary enterprise units. Too much reliance on electricity, once there is a power outage, will seriously affect the normal production and operation of enterprises. Gas-fired boiler is different, in all clean energy boilers, its comprehensive operation The lowest cost. Although electric drive boiler accessories are needed in ordinary operation, the dependence on electricity is not great, and diesel generator can be used to operate power driven boiler fittings in the state of blackout. Because gas particles fuel ignition point, is not flammable, so even if the stack in the aisle side also does not matter. Overall: gas-fired boiler is better, can save a lot of operating costs for enterprises, economic, practical and environmental protection, and its small shortcomings easy to solve the impact of little.
