Hot water boiler vaporization problem the whole solution 1, hot water boiler steam boiler of the phenomenon (1) boiler and pressure suddenly increased safety valve starts to emerge from the water and steam in the expansion tank. (2) the impact of sound water boiler, pipes to vibrate. Impact or the like occurs in the water (3) circulatory system piping. (4) a sharp rise in the temperature of boiler water, over-temperature signal overtemperature alarm occurs. 2, because (1) hot water boiler pot all the water vaporization operator negligence or misuse. Such as forced circulation hot water systems, at startup, the first boiler ignition, after the circulation pump. When shutdown, stop circulation pump, after stopping the boiler operation; or storage of fuel and heat in the boiler does not distribute all do, eager to stop the circulation pump is running and so grossly erroneous operation. (2) the occurrence of circulating hot water boiler outage, improper handling. (3) hot water boiler circulation system or severe leakage, device malfunction or constant pressure, causing a sudden drop in pressure in the boiler. This situation occurs mainly in the high-temperature hot water boilers. (4) cyclic interrupt occurs, although the boiler immediately stop running, but the remaining fuel in the combustion chamber and heat storage water vapor of the pan. This usually heat storage capacity in the furnace, the occurrence of a small pot of water volume of hot water boiler. (5) stop the pump sudden power failure or failure of the circulation pump. (6) the temperature of the hot water boiler, the pressure indicating instrument malfunction, resulting in erroneous judgment. 3, the reason the hot water boiler local vaporized boiler water (1) within the reservoir portion of the tube boiler scale or debris, the local destruction of the boiler water cycle. (2) a boiler structure unreasonable or undesirable combustion conditions, resulting in the line between the parallel deviation is too large heat boiler or boiler water uneven flow distribution, resulting in local overheating vaporized. Local and overall circulation circuit (3) can not form a natural circulation boiler, causing local overheating of vaporized water circulation circuit occurs once the pump stops and the like. 4, treatment of hot water boiler steam boiler (1) stops running hot water boiler. (2) Check the hot water boiler and heating cycle causes vaporization system, and processed. (3) hot water boiler and hot water heating system natural circulation loop, loop back to the natural valve open road. (4) When a sudden power failure, the pump stops running, stopping in the boiler water cycle (forced circulation boiler), the temperature of the boiler water continues to rise due to heat accumulation surface of the combustion chamber of the boiler water to steam, because of a large water capacity If handled properly, usually does not cause accidents pot of water vapor. For hot water boiler tube DC (most of this is domestically produced boilers), because of its small water capacity, when a sudden power failure stop the pump, resulting in more accidents pot of water vapor. Hot water boiler should have suddenly prevent or mitigate the pot of water vapor measures to stop the pump during a power outage. China is now using more is to add water to the boiler and the boiler outlet slow release of steam, the pot of water on the one hand to maintain liquidity, on the other hand reduce the water temperature, up until the elimination of the combustion chamber of the regenerator. Some install the spare circulation pump driven by the internal combustion engine, when a sudden power failure, start the engine, but poor when asked to take into account, because the engine is not instantaneous will be able to start. There is provided a self-standby power supply or generator.
For large and medium-sized enterprises which do not have heat supply from the central thermal power plant, when the continuous and stable steam consumption is above 20t/h, there are generally conditions for the establishment of self-provided thermal power plants. This kind of enterprise can choose 20t/h medium pressure boiler type or 35t/h medium pressure and sub-high pressure boiler, 1.5MW or 3MW back pressure type steam turbine-generator set, and build self-provided thermal power plant, which is mainly heating and auxiliary to generate electricity, and can obtain great economic benefits. Compared with the dispersed small-scale industrial boiler, the fuel consumption of the cogeneration is equal to that of the small-scale boiler due to the higher thermal efficiency of the boiler. Under the same heating conditions, it can be obtained by using co-generation of heat and power. Extra power.
Sinter cooler waste heat boiler is one type of waste heat boiler.ZG is a professional sinter cooler waste heat boiler supplier in china.In the process of steel production,the energy consumption of sintering process accounts for about 10% of total energy consumption,second only to iron-making process,list in the second place.Total energy consumption in the sintering process,nearly 50% of the thermal was emitted into the atmosphere at the sensible heat form of sintering flue gas and a cooler.The waste heat recovery of sinter cooler,is the latest set of power generation technology that through recycling flue gas heat of drop-tail or wind box of sintering machine and sealed section of sintering cooler and waste heat boiler to promote turbogenerator with low parameters to work.
This is our first collaboration with fast boiler, professional and caring service fast boiler's impressed us. From pre-sales advice to after-sales guidance, every step is very careful and thoughtful.
