First, we need to clear in the boiler "coal to gas" process, to determine the different rehabilitation programs depending on the furnace. Second, grasp the "coal to gas," the key link. 1, removal of the original coal-fired boiler slag machine, coal hopper, coal equipment, chain grate, gearbox and so on. 2, by calculating the heat transfer in the furnace, the furnace geometry is determined, the center position of the furnace flame. Re-casting furnace, furnace refractory concrete casting material used, a large ratio of aggregate: Aggregate: Small aggregate: Sand: = 4:2:1:1:2 refractory cement. After the boiler pipe arch to avoid the flame center position, after the original arch pipe elevation on the basis of the original slope. 3, installation of explosion-proof doors. For gas-fired boiler, the blast doors is an important facility to protect the safe operation of the boiler. 4, boiler water test of 1.25 times the working pressure. Third, no matter what kind of furnace should be noted that in the transformation of the construction of the following questions: 1, should guarantee the smooth flow of flue gas, have a good fullness and should avoid dead ends and dead. 2, the burner should be provided at the height position of the center of the furnace, and the combustion space and has sufficient length. Flame should not be flushed to the wall heating surface, so as to avoid incomplete combustion gases local overheating and damage to the wall. 3, since the combustion gas in the furnace backlash, high thermal strength, exposed to the bottom of the drum in the furnace should be adiabatic process. 4, various pipes, fire tube boiler furnace wall substantially refractory brick masonry, and shield plus insulation material. In the "coal to gas" should pay attention to the tightness of the furnace wall, minimizing the original door, door checks, etc., can assemble the refractory block, prevent cold air flames wounding or excessive leakage into the furnace , affecting boiler efficiency, to see the fire hole must remain closed also should see the fire hole, heat-resistant glass viewing by fire. 5, the furnace boiler and gas than coal-fired boilers, is generally greater, there is sufficient combustion space, increase the volume of gas, does not affect the transformation of combustion conditions. If the user requests output significantly improved boiler, the furnace can be increased radiation heating surface, to remove scale and soot while the inner surface of the outer heating of the original, so that without increasing the volume of the boiler case to improve the boiler output is not a problem. Thermodynamic calculations must do in the boiler, while the smoke but also good wind resistance calculation intensity calculation. Fourth, the correct choice of matching burner
Especially now inflation, such as water, coal and natural gas prices will only rise, and electricity prices will only be lower. Electric boiler products consume about 100 watts per square meter per hour. There are many responsible electric heating enterprises have a commitment, calculated according to 100 square meters of houses, from November 15 to March 15, a total of four months, the electricity bill does not exceed 2000 yuan. Ensure that the temperature is 18 to 22 degrees. If normal use exceeds local central heating.
Fangkuai Boiler is based on low-nitrogen energy-saving and environmental protection. It focuses on the development trend and uses universal excellent technology, products and services. According to such a method, it is now applicable to the development of society around the world, promotes cutting-edge work in the future manufacturing industry, and maintains the ideal use of customers in various industries.
Why regular cleaning industrial coal or biomass fired hot water boilers manufacturer: hot water boiler can be divided into many different depending on the application, tea and hot water boilers, hot water boilers, and so on. But each boiler after a period of time necessary to carry out regular clean-up, so as not to affect the normal use of the service life of the scale and the usual hot water boiler. Boiler water contains small amounts of salts, suspended solids and gas, the presence of these substances can cause such accumulation, corrosion performance, some time after the operation of the boiler water side will bear a small amount of calcium magnesium carbonate scale and corrosion and other products, these rugged dirt attached to the exterior of the boiler, resulting in improved heat transfer, increased coal, affect the operation of boiler efficiency, leading to higher economic losses to the safe operation of the boiler caused serious harm. Pickling descaling boilers necessary to stop the current, and finally to the inner wall of the boiler water clean side clean coal utilization rate of progress, while saving a small amount of coal, increased environmental pollution, extend the service life of the boiler. That the above things, you should understand the need for regular cleaning of the hot water boiler okay. Optimistic about the boiler safety valve, to ensure safety.
