thermal power plant boiler in siliguri
1, after receiving the task given row, PPE dressed, F bring special wrench, open the given row situ total gate.
2, once the door fully open, contact fireman DCS screen to open the corresponding electric door sewage, sewage finished, first off the secondary door, shut the door once, by-road in turn. All sewage finished, close the door once each sewage and sewage total gate
3, sewage, should pay close attention to the water level, the water level there is any abnormal or accident, they should stop the discharge operation.
4, sewage two hours, you should check whether each door core doors sewage leakage, such as leakage should quickly open the door once the sewage to drain the possible residue stuck in the door at the core, the same before the operation to contact and obtain consent boiler management .

Industrial 35 ton Coal Fired Boiler Technology Transform
Sinkiang Hengfeng Sugar Co. has two ZG-35 / 39- M8 in temperature and pressure in the chain grate boilers. Since the life of equipment has reached more than 10 years. And the two boilers are not at full capacity, lower boiler efficiency, high energy consumption. Especially with high-quality lump coal burning boiler needs in the field, the price of coal was 340 yuan / t, while the coal mine (goose mine) that is close to a large number of local mixed coal, this mix of coal calorific value (5 262 kcal / kg) and field quality lump coal calorific value (6 000 kcal / kg) similar, but cheaper 40 yuan per ton.
How the thermal efficiency of the thermal power plant boiler in siliguri in order to improve the TSGG0003-2010 "industrial boilers energy efficiency testing and evaluation rules" calculated in the thermal efficiency point of view: the thermal efficiency of the boiler ηj = 100% - (q2 + q3 + q4 + q5 + q6) where: Q2 is the exhaust heat loss, q3 incomplete combustion gas heat losses, q4 solid incomplete combustion heat loss, q5 is heat loss, q6 ash material is heat loss. To save fuel, improve the thermal efficiency of the boiler, common measures are the following: 1, the use of flue gas heat recovery technology to reduce exhaust loss of the main factors influencing the heat loss is the exhaust gas temperature. The higher the exhaust gas temperature, the greater heat losses. Currently, when most of the new boiler factory is equipped with flue gas heat recovery unit, such as economizers, half or full condensation condensing flue gas heat recovery device, these measures can effectively reduce exhaust gas temperature and improve the thermal efficiency of the boiler. 2, reasonable control air-fuel ratio, to optimize combustion and reduce the loss of incomplete combustion when the heat losses and the excess air coefficient is too high, excess equivalent of inhaled cold air into the furnace, this part of the cold air does not participate in the combustion of the excess, but vain drained after being heated, heat losses increase; cold air into the furnace as to continue to increase beyond a certain limit, the furnace temperature will be lowered, incomplete combustion can also cause loss increases. When the excess air coefficient is too low, the fuel can not get enough oxygen for complete combustion, resulting in incomplete combustion loss increases. The long-term severe incomplete combustion, boiler heating surface will result in carbon impact heat transfer efficiency, continues to increase exhaust losses. Therefore, the reasonable control of the air-fuel ratio to minimize heat losses and incomplete combustion losses q2 q3, is another key point to enhance the thermal efficiency of the boiler. 3, strict control of boiler water, boiler scale control SCIENCES water will contain various impurities and calcium and magnesium scale substances, boiler fouling inevitably. Low thermal conductivity of the scale, so that once the heating surface fouling due to increased thermal resistance, boiler exhaust gas temperature rises, heat losses will increase. Test data indicate that the boiler heating surface junction 1mm scale, heat losses will increase from about 2% to 4%, the thicker the scale boiler heating surface, the greater the resistance, the thermal efficiency of the boiler will be lowered more. Boiler fouling not only reduces the thermal efficiency of the boiler, and the boiler Heating Surface temperature rise, causing heating surface damage, and even cause boiler explosion. Therefore, high-quality soft water treatment apparatus, in strict accordance with the process operating boiler feed water softening devices, the control of boiler feed water quality, can delay scale formation. Meanwhile, boiler scale control in real time to master the situation boiler scale, a scale clean-up, if necessary, is also very important. 4, strengthen the insulation, to prevent leaking, reduce heat loss due to the boiler, the temperature of soda heat pipe system is better than the boiler room air temperature is high, some of the heat will be dissipated to the ambient air by radiation and convection, heat radiating boiler loss. Accordingly, when the insulation layer and the heat pipe boiler systems found damaged or leaking, it should be repaired, to reduce heat loss.
