After completion of the gas automatic diesel or fired boiler cleaning, be sure to use hot air to dry them, but not both for heating the furnace walls and other accessories, this is likely to have adverse consequences. Right way is to place an electric heater in the bottom of the gas boiler, heated.

Boiler precipitator technical principles of environmental protection and the development trend in recent years, the rapid development of gas power plant automatic diesel or fired boiler in the direction of large-capacity, high-parameter, either manufacturing or operations management have been close to the advanced level. Boiler and gas industry to maintain large, widely distributed, high energy consumption, heavy pollution, energy efficiency and pollution control the overall level compared with foreign countries have a certain gap, a huge energy saving potential. By the end of 2012, China's use of gas in industrial boilers 467 000 units, with a total capacity of 1.78 million tons of steam, the annual consumption of about 700 million tons of coal, accounting for over 18% of the country's total coal consumption. China's gas lower overall energy efficiency of industrial boilers, about 15 percent of its actual operating efficiency lower than the international advanced level, with great potential for energy savings. In recent years the rapid development of technology the dust bag, in particular accessory bag filter (dust bag, dust bag cage pulse valve, control of the PLC technology, etc.) to improve quickly, while baghouse 10% desulfurization efficiency can be improved It is dry boiler flue gas desulfurization one of the major thermal power plant equipment. Boiler precipitator dust is the most effective pollution control equipment. It has a high dust removal efficiency, after the flue gas-containing filter baghouse dust concentrations below 50mg / m3, even at 10mg / m3 or less, and can efficiently remove the fine dust particles. Boiler boiler precipitator not just in the production of which use can also be used in other fields of thermal power. During use of the boiler generating the flue gas and dust is inevitable, the boiler boiler precipitator dust is separated out from the flue gas, thus reducing the dust pollution and facilitate further flue gas desulfurization, denitrification process. Spark arrestor smoke dust is mainly used in some high temperature and flue gas containing process Mars. For example, the flue gas cupola, intermediate frequency furnace flue gas, a furnace flue gas and so on. The main role is to eliminate smoke sparks, to avoid burning dust bag. Spark arrestor has a variety of structural forms, cyclone, louvered like. The most effective way of collecting cyclone is, the guide vanes guide the flue gas using a cyclone-type rotational flow, after the dust and large particles Mars cylindrical guide vane duct wall collision or off. When the smelting furnace flue gas containing spark large particles, dust bag will cause damage. Mars trap can effectively trap particles Mars in the flue gas, the protection of the bag filter. The entire device by the PLC control unit, automatic cleaning, discharging and automatic temperature control and over-temperature announcer.

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 automatic diesel or fired boiler 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.
