vertical boilers in Europe

How to shut down a vertical boilers in europe in a normal way?

The normal shutdown operation of the steam boiler is to stop the supply of fuel, stop the supply of air, and then stop the air intake; close the pressure supply valve and then close the water supply valve; close the main air valve, open the steam trap; close the flue baffle.

Pressure hot water vertical boilers in europe because there is a certain risk, it is necessary to install a pressure gauge. 3, pressure hot water boiler is full of water, the water level does not need to consider the issue of control.

For a long time, the vertical boilers in europe and burner are attributed to two different sectors each R & D re-combination, but the overall performance of the gas boiler, there is a qualitative impact. Fang fast R & D team after two years, estimates adjusted 300 times, breaking the status quo burner and boiler production separate, optimized depth coupled combustion system and heat transfer system architecture, combined boiler and combustion system, combustion system and successfully developed the depth of the heat transfer system coupled "Euromonitor θ5", so that gas-fired boiler into a complete energy system, to achieve a qualitative leap. "Euromonitor θ5" additional air pre-heater, cold air through the heat exchange tubes and the body opening for the flue gas countercurrent heat exchanger, the exhaust gas temperature is lowered while saving fuel; using a condenser, economizer flue gas heat recovery, thermal efficiency of the boiler can be increased by 10%; the use of FGR flue Gas recycling technology and Ultraten wing technology, improve heat transfer efficiency, emissions of nitrogen oxides emissions standards in line with domestic cities.

How the economy heating stove manufacturers pulverized coal fineness determined? The means by which to adjust? How the economy heating stove manufacturers pulverized coal fineness determined? The means by which to adjust? Boiler burning pulverized coal fineness to have a significant impact. The finer the coal, coal combustion more secure, less unburned heat loss, to maintain high efficiency of the vertical boilers in europe, but the power consumption milling, metal consumption may increase, but also to advance the ignition of pulverized coal, flame furnace center reduced, it is possible to burn the burner nozzle. The more coarse pulverized coal, the milling steel consumption and power consumption is small, but the mechanical loss of incomplete combustion to increase. Thus, for a given coal and boiler plants, the presence of coal into the furnace a fineness optimum value, i.e. economic coal fineness. After milling to mechanical incomplete combustion consumption loss of the coal fineness is the minimum economic coal fineness, fineness of pulverized coal in the economy, loss of incomplete combustion boiler and milling power consumption and consumption of metal the minimum sum. Usually coal fineness can proceed from the following aspects adjustment; changing ventilation system; coarse adjustment splitter diverting baffle; changing the height of the coarse separator cone.
