After cleaning gas steam automatic 4000 kg boiler common method of gas-steam oven after prolonged usage will junction green coke, steam oven cleaning gas is steam oven for coking gas during use, problems of carbon deposition. It is a good solution to gas-steam oven cleaning affect the production of contradiction, and routine cleaning technology can produce a lot of wastewater problems. Here we look at the specific bar 1, Delayed Coking cleaning: after adding the diluted cleaning agent to the gas steam boiler system, fill the water level to the high slot 1/2. In addition to the amount of coke cleaning agent is added: 10-20%, determined according to the specific amount of scale thickness. Temperature: 90-95 deg.] C, time: 12-72 hours, can be determined according to the scale thickness. 2, the rinsing cleaning: steam oven gas cleaning system clean the rear end of the residual liquid, rinse added 2 times, until no foam cleaning agent in addition to the coke, water clarity is good. Temperature: 85-95 ℃, Time: 5-8 hours. 3, Chit steps of: cleaning the furnace gas and steam at the end of the gauge is connected or can be connected to other places air compressor, compressed air system to boost 0.3-0.4Mpa, in the low and vented, and so forth, until the water Chuijin so far.

How the thermal efficiency of the automatic 4000 kg boiler 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.

We learned that recently, the city of Wuwei in Tianzhu county government announced that it will carry out a comprehensive coal-fired automatic 4000 kg boiler demolition "clear" action aimed at remediation efforts to increase coal-fired boilers, and resolutely fight pollution control tough fight, complete coal-fired boilers out of the grid, clean energy transformation of the task of governance and compliance. The task of governance staff, shimenzhen government, Hua Temple town government organization done by the Bureau of Wuwei City, the ecological environment will Tianzhu Branch, and Hua Temple shimenzhen government and town homes for the elderly failed fork Station coal-fired boilers were concentrated tear down. To continue to improve the air quality of the environment, protect the health of the people made great contributions.

Tianzhu County will further promote the comprehensive improvement of coal-fired boilers, and through the elimination of the demolition, clean energy transformation, environmental compliance management, etc., with the completion of the internal area of ​​coal-fired boiler remediation tasks, achieve discharge standards in all coal-fired boilers. Meanwhile, the industrial park central heating, phasing out central heating, and for 10 tons of steam coal-fired boilers in the gas pipeline network coverage.

Up to now, Tianzhu County by incorporating central heating, clean energy transformation, compliance management, has completed the renovation of 74 coal-fired boilers. The remaining four coal-fired boilers in Tianzhu Force has developed a program of clean energy for heating reconstruction project, planned in June renovation, completed in August.

Various steam automatic 4000 kg boiler fuel costs are how much money? Now in many large factories which will use a variety of steam boilers, boiler when using these, we must burn certain fuels, or use some energy to be able to generate steam, in which case it must be spend a certain cost, at present, the country attaches great importance to environmental protection, many boiler fuel and energy used are natural gas or electricity, the use of these two raw materials for process needs to consume how much it costs?
