Accident horizontal steam heating steam atmospheric boiler three: an economizer tube and the explosion accidents, and bursting phenomena economizer tube (1) decreased boiler water level, water flow is abnormally greater than the steam flow. Sound leaks nearby (2) economizer, and the lower furnace wall gap outwardly steaming flue gate leakage. (3) the exhaust gas temperature drops, the color of white smoke. Wet ash hopper within a lower portion (4) of the economizer, there is severe water flow down. (5) the flue gas resistance increases, induced draft fan sound is not normal, the motor flow rate increases. 2, Economizer blasting process (1) For non Fractional economizer, such as when the boiler to maintain the normal water level, the water can be increased to, and close all valves and recirculation duct drainage valve to maintain the short run to be put into operation after the backup boiler maintenance shutdown. If the expansion of the accident, when the water level can not be maintained, should an emergency shutdown. (2) for separable economizer bypass flue damper should be opened, closed dampers, suspended economizer. At the same time open water economizer bypass valve, continue to water boiler. Smoke, the water reliably isolated from the water economizer memory immediately let go, the air valve opening or valve lift. Flue baffle tight, maintenance can be carried out under conditions to ensure personal safety, to resume operation, or should be shutdown before overhaul. 1, the phenomenon (1) in the boiler water hammer emitted boilers and pipes at a certain rhythm crash, sometimes loud sound, accompanied by strong vibration water pipes or steam pipes. (2) gauge pointer swings back and forth, consistent with the frequency of the vibration noise. (3) water hammer severe, may lead to the respective connecting members, such as flanges, weld cracking, breakage of the valve. 2, treated water hammer steam pipe (1) reduced steam supply, close the main steam valve if necessary. (2) Open the trap set on the superheater and steam pipe hydrophobic tank (3) the drum water level is too high, the sewage should be appropriate to maintain the normal water level. (4) strengthen water treatment work to ensure water supply and boiler water quality, prevent priming. (5) elimination of water hammer, status check and the frame pipes, flanges, etc., such as a warm-again without damage for the steam supply.

Hot water heating steam atmospheric boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).

Pharmaceutical select the high cost of steam heating steam atmospheric boilers do? Pharmaceutical select the high cost of steam boilers do? Generally, the steam boiler at the plant as long as the application is quite wide, then select the high cost of pharmaceutical steam boiler it? Xiaobian below take you to do a simple understanding. Under normal circumstances, we mentioned the cost is basically a comprehensive consideration of procurement costs and operating costs, steam boilers in the choice except boiler, auxiliary equipment required for the configuration is not so complicated, the basic is water treatment equipment, water mains , pumps (one with a prepared), burner, a chimney, electronic control devices. So when a user making a selection, if the brand of the boiler auxiliaries have requirements, then you will need to be considered depending on the circumstances, different natural high and low price, so the purchase price is naturally uneven, however, the normal price, for example, said one ton steam boiler will basically between 70,000 to 130,000, the price is relatively high, but considering the auxiliary brand, boiler technology costs, basically the price is more reasonable. Further, a running cost, in general, arranged cost pre-boiler is very high, running cost will be relatively low, and within a certain period of time, these cost constantly accumulated, which can reach the back of this effect, after comprehensive consideration of both, pharmaceutical and select the steam boiler cost is not high. In short, Xiao Bian personal feeling for pharmaceutical companies such, the normalization of earnings and the cost of thrift operators are generally considered relatively, on a long-term sense, steam boilers, whether in business or in their production cost savings are relatively with optional value.

Many of our urban centers to implement 30 mg / cubic meter of air pollutant emission standards, which for many is a challenge heating steam atmospheric boiler equipment. And no electric steam boiler combustion chamber and does not require a chimney, regardless of heat loss problems; as well as this clean, non-polluting properties, more environmentally friendly.
