With the increase of air supply volume, the mixture of oil mist and air is improved, which is beneficial to combustion. However, if the air volume is too large, the furnace temperature will be decreased and the incomplete combustion loss will be increased. At the same time, the heat loss of exhaust gas will be increased and the power consumption of the fan will be increased because of the increase of flue gas. If the air volume is insufficient, the combustion will be incomplete, resulting in carbon deposition at the tail, which is prone to secondary combustion accidents. Therefore, each industrial fired boilers should pass the thermal efficiency test to determine its economic air volume at different loads. In practice, the stoves usually take into account the ignition of the nozzle and the carbon dioxide or oxygen content in the flue gas. Content to adjust the supply air volume. If it is found that the combustion condition of a nozzle is not good, or if the atomization plate with different aperture is replaced, the air pressure of the supply duct should be kept unchanged, and the opening degree of the duct baffle of the nozzle should be adjusted to normal combustion. If the fuel quantity changes due to the change of the oil pressure in front of the furnace, the opening of the fan baffle should be adjusted to achieve normal combustion by changing the air pressure and air volume of the air supply duct when it is necessary to adjust the supply air volume.
3) the observation and analysis of all kinds of flame when adjusting the fuel oil. Generally through the fire point adjustment and flame center adjustment to complete the flame adjustment. The ignition point of the oil mist should be close to the nozzle, but there should be no tempering. Early ignition is beneficial to complete combustion and stability of oil mist. However, the fire is too early, too close to the nozzle, easy to burn the nozzle and furnace wall to determine the mouth. Furnace temperature flying oil varieties and atomization quality, as well as air volume, wind speed and oil temperature, will affect the distance and proximity of the ignition point. So if you want to adjust the ignition point, you should find out the cause in advance, and then take targeted measures. When the boiler load is constant and the oil pressure and oil temperature are stable, Should be based on the ignition point wind speed and wind distribution situation.
Gas-fired steam industrial fired boilers safety valve from installation to use, it must remain vigilant safety valve is one of the most important components of the gas steam boilers, boiler probability of the risk occurring due to various incidents can effectively suppressed. This article focuses on the safety valve from installation to use several important considerations, we do not ignore the use of gas when it steam boiler. A Notes 1 safety valve, the safety valve should be mounted vertically in a high position in the pot business, set box. 2, between the safety valve and the drum or header, not equipped with access to the steam outlet pipe and the valve. 3, the lever-type safety valve should prevent movement of the self-apparatus and the weight limit leverage deviant guide tube, a spring safety valve should lift and handle means for preventing movement of the adjustment screw is screwed lightly. 4, the rated steam pressure less than or equal to 3.82MPa gas steam boiler safety valve throat diameter of not less than 25mm; power greater than the rated steam pressure 3.82MPa boiler safety valve throat diameter not less than 20mm. 5, the safety valve and coal-fired steam boiler tubes, the cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve. 6, the safety valve should normally be installed exhaust pipe, exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. 7, the safety valve exhaust pipe at the bottom should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. 8, rated evaporation to 0.5t h coal-fired steam boiler /, at least two safety valves installed; Rated evaporation 0.5t h less than or equal to electric boiler /, mounted on at least a safety valve. 9, separable economizer outlet, the steam superheater outlet valve must be installed.
The fact that we determined to achieve cooperation with the fast industrial fired boilers is a very wise decision, after a period of time put into the boiler efficiency significantly much higher than our original boiler efficiency, significantly reduce fuel costs, the economic benefits brought by the boiler is obvious. --customer feedback
