Of all the heat losses in a chamber furnace, the heat loss from exhaust smoke was the largest, at about 4% and 8%. The main factors affecting the size of Q2 are exhaust volume and exhaust temperature. Exhaust volume is large, exhaust temperature is high, exhaust heat loss is large. In general, Q _ 2 increases by about 1% when the exhaust temperature is increased by 10 ℃ and 15 ℃. Reduce the exhaust temperature, can reduce the heat loss of exhaust smoke. But it is unreasonable and impermissible to lower the exhaust temperature. In order to reduce the exhaust temperature, the heating area at the end of the boiler will be increased, which not only increases the steel consumption, but also increases the flow resistance on the exhaust side, so it is necessary to consume more energy in operation. In addition, the exhaust temperature should be kept higher in order to reduce the low temperature corrosion of the tail heated surface, especially when the fuel with high sulfur content is used. Therefore, reasonable exhaust temperature should be determined by technical and economic comparison. For modern large and medium-sized boilers, the exhaust gas temperature is usually 110 ℃ 160 ℃.
The higher the pressure of the steam boiler, the higher the energy consumption, and the corresponding pressure on the steam equipment and the piping and valves will increase, which will make the maintenance and maintenance of the steam boiler relatively advanced. The share of steam that occurs during and during the process of heat transfer and lost will also increase. The salt contained in the high-pressure steam will increase with the increase of the air pressure. These salts will cause the structural appearance of the heated area such as the water wall tube, the smoke pipe and the drum, causing overheating, foaming, blockage, etc., and causing the pipe to blast when severe. Risky incidents.
1. Pay attention to the amount of fuel. Avoid more fuel in the boiler. If there is too much fuel in the furnace, the fuel will not be fully incinerated, and some incinerations that have not been completely incinerated will occur. If the furnace is found to be dark, the fire is small, and the chimney is emerging. Conditions such as black smoke are usually caused by carbon monoxide in the furnace.
2. The size of the incineration material used. From the point of view of incineration, the smaller the volume of fuel, the simpler it is to mix with air and simply incinerate. However, if the volume is too small, the energy consumption will increase greatly with respect to the gas-fired steam boiler, and the exhaust gas will increase, which will also cause the loss of fuel to a certain extent.
Steam Boiler WNS how much money a lot of enterprises in the procurement of the factory direct price boiler or when they consult the boiler manufacturer, is the first time you want to get information about the price.
