Boiler explosion: boiler accident points boiler and furnace two parts: an accident of boiler body is divided into five categories: crack, shrink flat, burning, swelling, cracks. The furnace in the fuel gas explosion accident. Which is hereby cause of the accident occurred and the case are as follows: Burst (called Rupture): boiler, due to negligence of the operator, or pressure allowed, or due to corrosion thinning, beyond their actuation can bear pressure, thus generating burst. Condensing flat (Collaps): Because the water level is too low, resulting in loss of overheating, cold water added suddenly, so that the steam condenses into water pot, is the volume is reduced to a vacuum, such as poor support, could not bear the atmospheric pressure outside, i.e., causing shrinkage flat. Burning (Burning): mostly burnt in the furnace tube, pipe and cigarette tobacco tube to tube plate joints. The reason for the operator to add too much fuel, the fire caused by excessive; or by the lack of capacity of the boiler, causing fuel to pay more due to the raging fire. Swell (Buldge): This is because the oil within the boiler or scale pan is attached to the steel plate or the heat can not propagate, causing local overheating (LocalHeating), decreased material stress plate soften, resulting in swelling phenomenon. Cracks (Crack): This is because: the boiler water is too alkaline formed caustic embrittlement (CaustivEnbrittlemnt). The steel material caused by impurities such as oxygen-containing laminate (Lamination). Thick steel plate, temperature difference is too large, the thermal expansion and contraction caused by stress corrosion, known as erosion groove (Grooving). As the gas blast furnace, the use of oil-based, gaseous fuel, exhaust gas poor, and the explosive range of the gas, causing an explosion.

(1) the internal environment of electrically heated vacuum phase change boiler is vacuum state when it is operated by electric heating vacuum phase change boiler. In this case, the oxygen in the intermediate water will be discharged to the outside of the electro-thermal vacuum phase change boiler, so the oxidation corrosion will not be caused in the boiler and the equipment will be damaged. At the same time, the heat exchanger part of electro-thermal china vacuum hot water boiler is made of stainless steel and will not be corroded. In addition, the electro-thermal vacuum hot water boiler only needs to add a small amount of heat medium water at one time, it will not increase or decrease during operation, so there will not be scaling in the interior.

Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing steam boiler. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.

Henan party fast fuel gas boiler characteristics of vacuum - What are the main characteristics of the vacuum boiler Henan party fast china vacuum hot water boiler: the so-called fast Henan square vacuum hot water boiler, also known as Henan party fast phase-change vacuum hot water boiler. Inside the medium pressure in the boiler is lower than atmospheric pressure refers to the normal operation, the boiler is heated by a cold phase change heat mode. ①, do not need to monitor the installation, the installation can be used; ②, a machine, saving investment; ③, non-corrosive (oxygen-free state in a vacuum), no cracks, no scars drum, not squib, long life (using the minimum strength is generally not less than 20 years life); ④, low failure rate, saving management costs; ⑤, lower than atmospheric pressure work, high safety; ⑥, using brass, stainless steel tube heat exchanger, sanitary water; ⑦, lower than normal operating temperature of the boiler, the heat exchanger temperature and pressure, high thermal efficiency, energy saving; ⑧, microcomputer control, a high degree of automation.
