industrial horizontal steam boiler in italy

Fluidized Bed

At the bottom of the boiler furnace there is a bed of inert material. Bed is where the coal or fuel spreads. Air supply is from under the bed at high pressure. This lifts the bed material and the coal particles and keeps it in suspension. The coal combustion takes place in this suspended condition. This is the Fluidized bed.

Why avoid the boiler burning pot often? This is because if the boiler is often fired, it will produce a large amount of scale inside the boiler, thereby reducing the thermal efficiency of the boiler. If more serious, it will also cause the boiler to burn out. In addition, if scaling occurs on the heating surface of the boiler, it will affect the transfer of combustion heat and increase the temperature of the furnace and flue gas. Under the pressure of the boiler, the boiler will have problems such as drum, tube explosion and so on. Therefore, it is necessary to avoid the boiler often burning pot, to avoid these problems.

Ukraine industrial construction quality, customer Ukraine's current visit to our company is very interested in industrial industrial horizontal steam boiler in italys. Our technical staff will fast one side condensing gas steam boilers, steam pipes condensing gas boilers and other star products, from performance to the advantage of his right to the customer. Natural gas is clean, easy to use and other advantages, is to use one of Ukraine accounted for a large amount of the type of energy. Fast boiler since its inception in 1998, with great concentration R & D and manufacturing of gas clean fuel boiler, has a very extensive industry experience, and to respond positively to the pace of global environmental development for the market launch of the gas boiler is not only the thermal efficiency is very high (up to more than 108%), emissions of harmful substances is very low (less than 18 nitroxides mg / m3).

Accident horizontal industrial horizontal steam boiler in italy 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.
