Emergency shutdown processing steps gas fire tube industrial boiler for steam distillation boiler will sometimes burst some cases, faced with the handling of the emergency shutdown. Xiao Bian summary of the situation based on past experience and measures to deal with the emergency shutdown of the boiler, to help you understand more fully the boiler. First, when the following conditions requiring emergency shutdown 1, vapor pressure exceeds the allowed safety pressure, stopping for gas taken, strengthen water supply, after the wind reduction measures, the pressure is still rising. 2, boiler water, water tables have not see the water level in the steam drum water level gauge steam valve closed or measures to increase the water supply, the water level is still invisible. 3, boiler filled with water, the water level has risen to the highest level of visibility, turn on the water but still no visible water level appears. 4, all the water table or pressure gauge all does not work properly. 5, all safety valves, sewage valve does not work properly all. 6, the boiler pressure parts, such as a drum, tube, water wall tubes is damaged, or when the personal security device crisis. 7, water supply equipment failure, nor spare. 8, while the furnace wall cracks during collapse danger. 9, delivery, induced draft fan damaged, can not continue to run down. 10 other events a serious threat to the safe operation of the boiler. Second, the emergency shutdown processing step 1, quickly turn off process. First shutdown burner, and close the gas supply valve to stop gas supply, and then cut off the valve, and finally opening the air exhaust valve or safety valve down precipitation. 2, rapid cooling furnace water treatment. After the shutdown can not continue to feed water to the boiler. When there is no water leakage or water, the cooling time can be shortened, accelerated cooling rate, cooling down the sewage water through alternate methods, and maintain the level. When the boiler is severely short of water, the method can not take rapid cooling, water supply to the furnace is prohibited to continue, otherwise there will be risk of explosion occurred. When the boiler is full of water, should be reduced combustion (fire thought into a small fire), open the drain valve turn on the water, while the opening of the trap on the main and sub-cylinder steam pipe to prevent steam away large amounts of water to produce water-flushing . 3, during shutdown, so that the furnace is not cooled too fast, to prevent the flue gas, the pressure receiving member and other member by inflation port being damaged by quenching.

The hot water fire tube industrial boiler for steam distillation can provide a large amount of high pressure hot water, wet steam and superheated steam, but it can achieve a pressure of only 32 bar. Under today's technical conditions, the hot water temperature can reach 240 ° C, and the steam flow can reach 45 t / h. From the current popular point of view, the use of fast steam boilers to provide wet steam is the most ideal solution: compared to the wet steam provided by the former (relative humidity 2% to 3%), the relative humidity of the wet steam provided by the fast steam boiler is only 0.5%, which reduces the risk of steam condensation in the steam line and has very good heat transfer performance when used.

Gas fire tube industrial boiler for steam distillation furnaces and cooking formal operation of the boiler furnace 1, and its object is to clear the body of the boiler impurities, grease and rust. The inspection of boiler installed and cold test run, each member confirms perfect safety conditions have hot start operation to start cooking stove. 2, boiling out dosage (see table below) Unit: kg / t rust grease Drug Name Notes thicker thin rust grease sodium hydroxide (NaOH) 2 ~ 33 ~ 4 trisodium phosphate (Na3PO412H2O) 2 ~ 33 ~ 4 when no trisodium phosphate, sodium carbonate can be used (of Na2CO3) in place of an amount of 3 to 6 kg / t water. 3, when dosing, the low water level in the boiler water should, boiler water should be the highest level, the drug was added on the stove interfaces (e.g., valve opening) when the cooking stove. 4, the end of the cook should the boiler furnace pressure was kept at about 75% of the working pressure, time is generally 2 to 3 days. 5, during the cooking stove, boiler water periodically take laboratory analysis, alkalinity boiler water of not less than 45 meq / L, should be added or dosing. 6, oven cooking is completed, the drum and the current tank should be cleaned precipitate, rinsing the boiler and in contact with the agent through a valve, to check whether or clogging sewage. 7, after cooling boiler, furnace water will be fully released. Open manholes, hand holes, repeatedly washed with water until the furnace no rust, grease qualified. (Ix) a test run, the test run should be with a load, for 4 to 24 hours (set maximum, minimum operating pressure). 2, observe the safety valve and various safety accessories, protective devices and other operations are sensitive and reliable. 3, after the commissioning of qualified, supervisory inspection agency should be acceptance.

Hot water fire tube industrial boiler for steam distillation is the essential equipment of our hotel, one of the parties to provide fast condensing pressure hot water boiler immediate operational effect. Our demand for environmentally friendly and out of the hotel itself, very high environmental performance requirements for boilers, party fast products fully meet our needs, the index after testing are in line with the relevant provisions of the State; with the outside atmospheric pressure remains stable sufficiently improved security index boiler, eliminating our worries. --customer feedback
