heat exhaust gas boilers

Coal-fired heat exhaust boilers gas conversion costs budget analysis

Under pressure "atmosphere 10" The premise of the policy and the current environmental situation of coal to gas expansion work is now in full swing up. So the transformation of the capital budget for gas fired boiler is how to conduct it? This is basically the transformation of the former coal-fired boilers for each client during prepared to do the necessary work. And today we talk about making a few parties need to pay attention when gas fired boiler reconstruction budget

Blue Sky Battle horn started, our country constantly walking on the green road. Reduce atmospheric emissions of nitrogen oxides, improve air quality, but also the people a blue sky, the industry has invested in the construction of environmental protection go, Guizhou Baiyun Quan Lake Hotel is no exception. As we all know, fast heat exhaust boilers R & D in the field of clean fuel boiler never stopped, through market research and screening, Guizhou Baiyun Quan Lake Hotel in October 2017 signed a low-nitrogen Thalia T5 series vacuum hot water and fast boiler boiler for hot water supply and heating the hotel.

In fact, the heat exhaust boilers "coal to gas" fully able to achieve energy, mainly reflected in:

1, high combustion efficiency

6 tons adjusting a combustion gas steam heat exhaust boilers, 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.
