Matters needing attention in loading and installation of Gas-fired Steam Boiler
Gas-fired steam boilers are a very wide range of special equipment, usually built in boiler rooms. However, in the process of loading and installation, some problems must be paid attention to, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
What anti-corrosion measures SZS water-tube boilers are divided into specific fire-tube boilers and water tube boiler structure according to the classification of the boiler body, according to the type of boiler fuel classified as a coal-fired boiler, oil boiler, gas boiler. Process boiler operation will have a certain degree of corrosion. Found sulfide under high temperature conditions, the flow of chloride ions and high temperature flue dust contained in the friction member is the main cause of corrosion of the boiler. A, for water-tube boilers, corrosion occurs primarily at the water wall or furnace wall, the temperature is higher. In particular, severe corrosion, heat utilization is low, less than 50% thermal efficiency. High temperature coating far-infrared radiation, high temperature up to 1700, may be maintained at a high temperature high emissivity, holding about 0.9, dense coating, excellent corrosion resistance. Second, for the fire-tube boiler, the corrosion occurs mainly on the water wall. Corrosion of high temperature oxidation and corrosion of various impurity ions sulfur, chlorine, fluorine ion etching, and abrasion dust in the flue gas. Can effectively increase the boiler water wall heat exchanger, the temperature of the water wall tubes can be reduced, slowing the rate of corrosion. Third, the external boiler, security risks caused by high temperature oxidation corrosion and high-temperature operating environment is client concerns, has a low thermal conductivity, purely inorganic coatings, environmental protection, can effectively prevent heat conduction, that is, to avoid the heat energy waste is also working to reduce the security risk operating environment. Fourth, the exhaust heat boiler, the flue gas condensation by corrosion is mainly caused by friction and dust. And flue gas heat exchanger during brushing energy corresponding high temperature coatings, protective substrate, extend the life of the substrate, saving energy resources, greatly reduce costs.
Inner Mongolia Autonomous Region for the winter heating long-term, large coal consumption of the actual situation, "strictly control coal pollution" as a top priority to improve air quality.
According to statistics, in 2018, Inner Mongolia fully complete the remaining 10 127 tons of steam / hour and small coal-fired boilers out of the task-level urban built-up areas; Hohhot, Baotou, Wuhai more polluting coal and other built-up urban area start 35 steam tons / hour and the phase-out of coal-fired boilers.
Inner Mongolia this year also completed shantytowns 142,000, an increase of central heating an area of 11.36 million square meters, the "coal to gas," "coal to electricity" pilot project, the region cut loose coal burning 636,300 tons.
In addition, in order to fight the "Battle of the sky" tough fight, Inner Mongolia this year has introduced the "Atmospheric Pollution Prevention Act," "Blue Sky Battle win three-year action plan to implement the program" and other local laws and regulations.
From January 2018 to November, Inner Mongolia Autonomous Region average PM2.5 concentration of 30 micrograms / cubic meter, down 6.3%, the ratio of the number of good days to reach 83%.
6 ton oil fired steam boilers has double drums. 6 ton oil fired steam boiler has membrane water wall, convection tube and flue gas condensate recovery unit. Horizontal oil fired steam boiler adopts “D” type structure design which is nice and convenient to transport.
