hot water electric generator
China is the large number of small coal fired hot water electric generators, 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.
How to pick wine hot water electric generator evaporation? Currently used for brewing boiler is divided into a lot, and some regarded as a steam generator and a small boiler for small wineries in the line of wine. For large wineries who need to purchase a large steam boiler production. For a selection of local wine boiler for businesses it is now more difficult of. Because many wineries required is not too clear about their current actual amount of steam late and needed. In this regard, fast boiler for the actual situation of the winery understanding, combined with the current amount of evaporation and the latter may expand production after the evaporation of accounting are required, draw the winery with two tons of steam boiler can be of.
Oil-fired hot water electric generators include oil-fired water boilers, oil-fired hot water boilers, oil-fired heating boilers, oil-fired bath boilers, oil-fired steam boilers and so on. Oil-fired boilers are boilers fueled by light oil (such as diesel oil, kerosene), heavy oil, residual oil or crude oil. Compared with gas-fired boiler and gas-fired boiler, oil-fired boiler runs more economically than electric heating boiler and is more convenient to use than gas-fired boiler. With the development of economy and social progress as well as the improvement of people's awareness of environmental protection, coal-fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers and oil-fired boilers. Gas fired boilers, etc., electricity Heating boiler operation is the most expensive, gas-fired boiler needs to be opened with gas pipeline, then, if there is no natural gas pipeline, but also hope that the operation cost of the boiler is low, only the choice of fuel-fired boiler. Oil-fired boiler is heated by burners, fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving. After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with coal-fired boiler with the same parameters and capacity, the thermal strength of furnace volume can be doubled. However, in order to reduce the heat load in the combustor zone, the water wall tube in this zone is avoided. Because of the overtemperature, the furnace volume is only reduced by about 1 / 3. Moreover, because the ash content in fuel oil is very little, it will not be slagging on the convection heating surface, so the flue gas temperature at the furnace outlet can be as high as 1300 ℃, and the pitch between tubes on the convection heating surface can be reduced to increase the flue gas flow rate, thus the heat transfer coefficient on the heating surface can be increased. Save heating area and steel. In order to prevent spontaneous combustion of carbon black oil scale on economizers and air preheaters, steam soot blowers should be added to these parts to keep the heating surfaces clean. At the same time, because the fuel oil does not form coke slag, the membrane water-cooled wall can be used to form a micro-positive pressure (500 x 1000 cow / ml). A boiler. It can save the draft fan, only the fan can exhaust the flue gas out of the furnace. If the whole shell of the boiler is made of thick steel plate, it can also be made into a positive pressure (0.3 ~ 0.6 MPA) boiler, which can make the whole structure of the boiler more compact, and is more used in the gas-steam combined cycle generator set.
Fangkuai Group has more than 60 independent intellectual property rights, advanced clean fuel hot water electric generator manufacturing technology, and jointly established a clean fuel boiler production, research and research cooperation base with Tsinghua University and Xi'an Jiaotong University. An enterprise with a R & D and test center for clean fuel boilers. The thermal efficiency of “Fangkuai” boilers can reach 107%, which has been included in the national special equipment energy-saving catalog. The company developed ultra-low nitrogen full premixed combustion condensing boilers and ultra low nitrogen emission fuel gas boilers, which are developed by the company using Ultran condensation technology.
