6, the implementation of pollution control industrial furnaces special action. City casting, iron alloy, metal smelting and regeneration, glass, ceramics, tiles, refractory materials, lime, waterproof materials, fertilizers, inorganic salts, calcium carbide, etc., according to the melting furnace, the melting furnace, sintering machine (furnace), baking ( calcined) burning furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace nine types of trades to carry out an intensive investigation. Closely integrated with the second census of pollution sources, establish a management inventory end of June 2019.
Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. 1, why chemical cleaning of newly installed and overhauled boilers? In the process of manufacture, transportation, installation and maintenance of boiler, it is inevitable that some impurities such as dirt, iron chips, welding slag, iron oxide and so on will be produced and glued to the pressure parts of the steam and water system in the process of manufacture, transportation, installation and maintenance. As soon as these impurities enter the steam-water system in operation, they will do great harm to the boilers and steam turbines. Therefore, the boilers before they are installed and overhauled must be chemically cleaned to remove them. 2. What are the rules for the time and temperature of water supply before boiler start-up? Why? The inlet speed of boiler before start-up should not be too fast, usually no less than 4 hours in winter, 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet water temperature of a cold boiler is generally at 50 ℃ 90 ℃, so that the difference between the feed water temperature entering the drum and the wall temperature of the drum is less than 40 ℃. The inlet water temperature of the uncooled boiler can be compared with the drum wall temperature, and the general difference should be controlled within 40 ℃, otherwise the inlet water speed should be slowed down. The main reasons are as follows: (1) because the drum wall is thicker and the expansion is slow, the tube wall connected to the drum wall is thinner and the expansion is faster. If the inlet temperature is too high or the inlet speed is too fast, it will cause unevenness of expansion, crack of welding joint and damage of equipment. (2) when the feed water enters the drum, it always contacts the lower wall of the drum first. If the difference between the feed water temperature and the drum wall temperature is too large, the speed of entering water is fast, the upper and lower walls of the drum and the inner and outer walls will produce a larger expansion difference. Cause large additional stress to steam drum, cause steam drum deformation, produce crack 3 when serious, how does the low temperature corrosion of tail heated surface produce? Formation of SO2,SO2 from sulfur Combustion in fuel combined with oxygen in flue Gas to form SO3, when the temperature of the heating surface is lower than the dew point of the flue gas The steam in flue gas is combined with SO3 to form sulphuric acid steam, which condenses on the heated surface and results in low temperature corrosion of the heated surface. The cold end of air preheater is prone to low temperature corrosion. 4, when the emergency shutdown? (1) when the drum water level exceeds the limit. (2) when all water level gauges of the boiler are damaged. (3) explosion of superheated steam pipeline, reheated steam pipeline and main water supply pipeline. (4) when reburning occurs at the end of the boiler. (5) all suction, fan and air preheater stop operation. (6) when reheating steam is interrupted. (7) Boiler pressure rises to safe door operating pressure, and all When the safety door refuses to move. (8) when an explosion occurs in the furnace or in the flue causing serious damage to the equipment. (9) when a boiler extinguishes a fire. (10) when a fire breaks out in the boiler room, it will directly affect the safe operation of the boiler. (11) when the furnace tube blasting cannot maintain the normal water level of the drum. (12) when all operator stations are blackscreen or crash at the same time and the main parameters are out of control. 5, how do I flush the drum water level meter? There are three processes for flushing the water level gauge: water side flushing: opening the drain gate, closing the steam side door, opening the water side door; steam side flushing: opening the discharge door, closing the water side door, opening the steam side door; Open the discharge door, open the steam side door, open the water side door. Rinse and close the drain door.
Careful maintenance of the boiler operators will have to do from the outside in, water quality management is also an important step in the maintenance of low nitrogen gas boiler. If the boiler water concentration is too high, it will lead to false water level phenomenon, resulting in the boiler does not work. Therefore, operators also need to strengthen water quality management and take preventive measures, so it is more conducive to long-term maintenance of low nitrogen gas boiler.
Combined with China's current situation, the provinces and cities have environmental requirements. General requirements for a gas-fired boiler increases: low nitrogen. Condensing technology now used in the fast side is one of the primary techniques to reduce nitrogen oxides (abbreviated NOx) in. If NOx emissions do not meet state regulations, it is absolutely not allowed to be used, even after running for some time, EPA will be ordered for low-nitrogen transformation or elimination process.
