industrial steam boilers cusine original in hongkong
It features electric boiler steam electric industrial steam boilers cusine original in hongkong characteristics: 1, electric steam boiler automatic intelligent control technology, no staff on duty. Flexible work can be set to manual or automatic mode. 2, the electric steam boiler can be automatically set according to the boiler operation time period of a day may be provided a plurality of different working periods, so that each heating boiler starts automatically sharing group, the group switching cycle heating, the respective contact time, frequency same, increase equipment life. 3, controller electric steam boiler pressure control, calculation, tracking, on the feed pump may be electrically heated tube automatic start and stop control when the load changes, may be manually controlled. 4, electric steam boiler with a number of complete protection, leakage protection, water protection, ground fault protection, steam overpressure protection, overcurrent protection, power protection, boiler automatic protection, safe home. 5, the electric boiler steam boiler steel boiler and pressure vessel, the vertical furnace, girth welds are welding, and X-ray detection, small boiler furnace, mechatronics, easy to install and mating; large boiler furnace sub-body design with electric control, to prevent electrical control affected by the high temperature furnace, to ensure stable operation of the electronic control means. 6, electric steam boiler heating element of low heat load surface meet JB / 2379-93 and "metal tubular electric heating element technical conditions" requirement. Thick stainless steel high electric wire outer tube, the inner tube is filled with the high purity magnesium oxide, electrically heated tubes and long service life. Each heating element flange connection, has a simple structure, high mechanical strength, safe, reliable, easy to replace and so on. 7, electric steam boiler compact structure, scientific and rational design and advanced manufacturing technology, the small boiler space and easy to transport and saves space. 8, the electric steam boiler no noise, no pollution, high thermal efficiency, high quality and efficient boiler insulation material be insulated, heat loss is small, energy saving. 9, electric steam boiler packaging using famous color plate package design, elegant appearance, easy to rust.
The technology of the fuel divided into three regions: the primary combustion zone (main combustion zone) reducing weakened; fed again in the second combustion zone fuel, it presents reductive; third combustor into the combustion air required for the remaining complete burn-up process, in order to achieve staged combustion of fuel and air. Using this technique, we can reduce NOx emissions from gas-fired boiler more than 70%.
Comprehensive analysis of the emergence of a chemical plant boiler explosion: comprehensive analysis of the emergence of a chemical plant explosion accident 1 boiler, chemical plant boiler explosion hazards appear extent boiler explosion is an explosion drum major, it has a great destructive force, will cause serious property damage and casualties. We must resolutely put an end to such incidents. Boiler explosion energy is mainly water evaporation, followed by steam expansion. After the pot of water loss of pressure, due to the sudden drop in saturation temperature, had been in a saturated water will evaporate quickly at higher pressure, about 1000 times the volume of the explosion pressure expansion to create a strong shock wave. Therefore, it has great destructive power. 2, the cause of the explosion accident analysis (1) gauge malfunction, boiler chemical plants are not allowed to appear; safety valve does not operate. (2) off the venturi fireman who do not pay attention to monitor, failure to close the main steam valve and a safety valve. (3) compressing the defective element itself or damage, after the development of a certain degree, such as reducing the steel corrosion wear, and the further development of defects formed in the manufacturing, repair, welding, or the material defect itself , dirt and heat transfer in the boiler poor, poor water circulation. Damage, overheating heating surface, a decrease in strength. After the boiler water, illegal operation will bring water boilers, boiler leading to sudden cooling and so on. 3, chemical plant boiler explosion accident prevention measures appear during boiler operation, should pay particular attention to the following points: (1) boiler load must be kept stable, secure attachments must be sensitive and reliable; (2) to strengthen the responsibility of the person in charge of the boiler work closely monitoring water levels, prevent the boiler water, to ensure the normal operation of the boiler. Low level alarm and low water sensitive and reliable chain protection, to prevent leakage. Water treatment (3) to take effective measures to ensure water supply and boiler water quality and prevent pollution, serious pollution.
