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.

Steam boiler heat loss is what causes? Steam boiler heat loss caused to the user a lot of burden, whether it is hot steam boiler what is causing the loss of it? To analyze together with you today. Specific causes heat loss of the steam boiler at several: 1: heat loss of exhaust energy: smoke exhaust gas boiler comprises means losses are not completely absorbed by the steam heat loss. How caused? Short distance high temperature flue gas fan suction force is too high, the high temperature flue gas immediately excluded from the boiler; a small heating area, high temperature flue gas boiler can not be sufficiently absorbed. 2: the fuel gas does not completely heat loss: the combustible gas discharged from the flue gas generated in a boiler, the fuel in the combustible gas or gaseous fuel combustion process itself does not contain all of the incomplete combustion releases heat losses arising. As the incomplete combustion of carbon monoxide and carbon dioxide containing off-gas produced by combustion compared to the complete, only a quarter of the amount of heat released. 3: Solid incomplete combustion heat loss: refers to the solid fuel combustion process as a fuel grate down the drain does not release the heat of the flammable substance and ash contained in the combustion of the fuel can not completely burned released heat loss caused. 4: Loss steam boiler Grate: refers to the internal heat loss of the absorbent. 5: high temperature heat loss: Indicates high water temperature and hot water temperature, heat loss. 6: heat losses within the 1ton steam generator tube due to furring bilingual.

The party soon provide us with three hot water boiler output foot, gas combustion, efficiency is very high, for us to save a lot of fuel costs. Moreover, these hot water boiler can be achieved by adjusting the full 24 hours a use hot water to meet the daily needs of old people. --customer feedback

Oil-fired boilers 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.
