energy saving gas fired condensing gas boiler

6 tons adjusting a combustion gas steam energy saving fired condensing boiler, normal combustion boiler three basic aspects of indicators include a uniform supply of the fuel, reasonable ventilation, adjustment the combustion. 1, to maintain the high temperature of the combustion chamber temperature of the upper layer is preferably in the 1100 ~ 1300 ℃, flame orange in color. Flame reddish color indicates that the amount is not enough to the wind, the color white indicates that excessive wind. It should be appropriately adjusted. 2, fuel ash to reduce ash content in the combustibles to be below 10%. 3, reducing the temperature of the boiler flue gas exhaust gas temperature should be controlled below 200 ℃. 4, holding furnace negative excess air boiler is 1.2 to 1.4, by adjusting the balance of the blowers to maintain the furnace pressure is -20 ~ -30Pa. 5, the thermal efficiency of the boiler to improve the thermal efficiency of the boiler should be kept above 60%. II. Combustion Adjustment 1, the amount of fuel to air required for combustion and the amount of a reasonable distribution. Ventilation should first increase the amount of fuel increases, it should first reduce the amount of fuel supply reduced ventilation. 2, the thickness of the seam and seam thickness configuration grate speed is 80 ~ 120mm grate speed at high, middle and low profile configuration of several commonly used methods:. 9a rapid combustion of thin seam b c thick seam in low combustion. 3 thick seam combustion speed, the segment with the wind blowing principle: burn promoting intermediate ends. That is, after the coal into the coal starts to warm up the shutter, fire line front arch, the primary combustion zone, the middle grate to burn the rear grate zone. Normal combustion conditions are: fuel from the coal at the beginning of the fire shutter 300mm, uniform flames, the fire bed formation, at the end of combustion from the end of the grate 300 ~ 500mm. 4. maintain proper furnace temperature to avoid coking. The fire bed to maintain the homogeneous combustion, to avoid burning fire bed obliquely. 6. The residence time of the fuel on the grate in less than 30 minutes.

Circulation

Fine particles of partly burned coal, ash and bed material are carried along with the flue gases to the upper areas of the furnace and then into a cyclone. In the cyclone the heavier particles separate from the gas and falls to the hopper of the cyclone. This returns to the furnace for recirculation. Hence the name Circulating Fluidized Bed combustion. The hot gases from the cyclone pass to the heat transfer surfaces and go out of the boiler.

8 ton condensing fuel gas-fired energy saving fired condensing boilers in Russia

ZG boiler re-export project—a full set of 8 tons of condensing fuel gas-fired boilers was exported to St. Petersburg, Russia. As the economic power of Russia, St. Petersburg takes industry as the main development point, and is a highly developed international city of science, technology and industry. Therefore, the selection requirements for production equipment are very high. The ZG boiler oil and gas boilers feature the internationally popular classic “all-wet-back three-return” design structure, FRG flue gas recirculation, condensation prevention and control, and other special technical advantages to enable Russian customers to successfully sign a complete set of 8 tons of WNS with ZG boiler within a week. Type saturated steam boiler contract, the fuel is natural gas and diesel. In addition, based on Europe's strict boiler emission standards, ZG boiler has configured pure Italian imported burners for customers.

For more than two decades, it has been the focus on clean energy saving fired condensing boilers, the insistence on precision and wisdom, and the pursuit of exquisite craftsmanship that have made today's Fangkuai boilers. Fangkui Boiler will always be based on the boiler industry, and will return customer support and trust with brilliant results and sophisticated technology.
