vertical flue fire tube boiler structure
Industrial vertical flue fire tube boiler structures prevent scale measures what? Industrial boilers prevent scale measures what? To ensure that no knot or less furring industrial boilers, water treatment work must strengthen measures usually taken include the following items. (1) pretreatment of raw water in the raw water to be taken using the coagulating sedimentation, filtration, purification and the like. (2) the outer pot pot water treatment comprising oxygen and softening process. Raw water often dissolved oxygen, carbon dioxide and other gases, is likely to cause boiler corrosion. Industrial boilers generally use heat deaerator, water for Ca2 +, Mg2 + and other harmful ions often used ion exchange softening. (3) pot-treatment chemical is added directly into the furnace slag fluidity reaction occur through ionic water chemicals with the furnace, and then discharged through the sewage in time. This method is suitable for small-scale low-pressure boilers. (4) Operation reasonable industrial boiler blowdown during operation, due to the continuous delivery of external steam, boiler water is reduced, resulting in increase in solid concentration in the furnace was dissolved, a precipitate gradually accumulated and formed in the long term high temperature scale, so We must be regularly sewage, reducing scale production. If it is found in boiler water alkalinity is too large, increase the sewage; on the contrary, should be reduced.
Fourth, the heat loss
Boiler operation, the temperature of the furnace wall and the outer wall of the boiler body is always higher than the temperature of the surrounding air, because this part of the difference in temperature will cause heat loss and radiation loss is formed. The outer area of the boiler and heat loss, the degree of thermal insulation, the outside air temperature and air flow rate of about size. General requirements of the wall surface of the furnace temperature should not exceed 50 degrees.
What are the main hazards and countermeasures gas steam vertical flue fire tube boiler structure there? Although gas steam boiler is essential for the production of many enterprises power supply equipment, but in practical applications of gas steam boiler danger also exists, therefore, fireman operation of the boiler must have professional credentials and job experience. Following on from a wide variety of gas steam boiler manufacturer to introduce measures to deal with and what are the main danger there. 1, when the boiler water to dry gas steam boiler when the water level is below the limit, the exhaust gas temperature rises and a boiler top will produce burning smell, we have been able to see the red-hot waterwall tubes from the door, tube also serious distortion even burst pipes, and can hear the explosions, smoke and steam discharged from the door to see the fire door. After this occurs, the supply of fuel should be stopped and a blower, extinguishing water into the furnace, if necessary, but be careful not to water boiler in such case. 2, if the boiler overpressure gas steam boiler steam pressure rises sharply and exceeds the allowable operating pressure, the pressure gauge pointer over the "red line", the safety valve, when the pressure is still elevated on the issue of overpressure alarm, steam but with an increasing temperature will reduce the flow of steam. If this dangerous situation, should weaken rapidly burning, gas steam boiler manually open the safety valve or vent valve to increase water supply, sewage increase, reducing the pot of water to reduce the temperature of the boiler drum pressure. 3, water wall boiler tube can hear a distinct blast tube pops sound or jet, pressurized combustion furnace by the combustion pressure becomes far, and has a vapor from the flue gas and can not see where fire doors and close the door, etc. ejection. If the furnace gas steam boiler tube rupture is not serious and can maintain the level, not to expand the accident, it can reduce short-term load operation, if it is serious burst pipe and the water level can not be sustained it must be an emergency shutdown. Hot gas steam boiler manufacturers to introduce the main boiler of several dangerous situations and corresponding measures. If the boiler water shortage occurs, the overpressure and burst pipes are extremely dangerous if not handled properly it will lead to serious accidents, so enterprises must be very careful when using gas steam boiler, the dangers to a minimum.
It is quick to understand our side of the vertical flue fire tube boiler structure, boiler and industrial furnace is Haimen sulfur dioxide, one of the important sources of emissions of nitrogen oxides and soot, boiler and industrial furnace to carry out remediation is to control total energy consumption, air pollution control, energy conservation an important measure low-carbon development.
Recently, Haimen government issued the "2019 Haimen boiler and industrial furnace remediation work plan" put forward requirements on the city's boiler and industrial furnace remediation work.
First, the target for the full year to complete the remediation boiler remediation tasks. DiBiao transformation of ultra-low emissions before the end of the year, the city's 2 sets of 35 tons of steam / hour or phase-out coal-fired boilers clean energy alternative to complete 2 sets of 75 tons of steam / h coal-fired boiler and 1 biomass boiler, completed 6 low nitrogen gas-fired combustion units transformation. Phase out coal-fired boilers to consolidate existing achievements regulation to prevent 20 tons of steam / hour resurgence of small coal-fired boilers.
Second, accelerate industrial furnace remediation. This year, the city's 32 industrial furnaces in accordance with the "out of a group, instead of a number, a number of governance" principle fully complete the comprehensive remediation tasks, promote the upgrading of industrial furnace and pollution reduction. And products of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln) and the like, according to cut-off high-pollution fuel combustion zone management requirements, the use of clean energy and heat plants, district heating Alternatively heat or the like.
Scheme requires 20 December, the district town organize and complete acceptance of the unit boiler and industrial furnace remediation tasks. Boilers have been removed embodiment physical treatment, use can not be recovered; coal-fired boilers use gas, electricity, light oil clean energy and stable operation of a month or more. Gas-fired low-NOx combustion transformation, the transformation of ultra low emission biomass boilers and coal-fired power boiler ultra-low emission transformation, to have construction contracts and construction unit transformation, after the completion of the transformation have qualified environment monitoring report. After the renovation of industrial furnaces to natural gas, electricity, light oil clean energy, the furnace can not be used and the coal and its products. Boiler and industrial furnace remediation in line with production safety regulations.
