Information

1. The first is to choose a boiler, pay attention to the following three aspects:

1. The design of the coal type suitable for the boiler unit is based on the design of a certain representative coal type. The selection of the boiler must pay attention to the coal type in the region. In addition, the new type, high thermal efficiency, and high degree of automation must also be selected. boiler.

2. Parameter selection The boiler generally has the highest efficiency at 80% -90% of the rated load. As the load decreases, the efficiency also decreases. Generally, the capacity of the boiler is 10% larger than the actual steam consumption. If it is not exactly the series standard, the boiler with a higher parameter is selected. The selection of the boiler auxiliary machine should also refer to the above principles to avoid "big horse carriage".

3. The principle of quantity selection is to consider the normal maintenance of the boiler and stop the furnace, and pay attention to the number of boilers in the boiler room is not more than 3-4.

Second, the boiler must be equipped with an economizer In order to reduce the heat loss of flue gas and improve the thermal efficiency of the boiler, the economizer heating surface is set at the rear flue of the boiler, and the heat of the flue gas is used to heat the boiler feed water to achieve energy saving purposes. , Increase the temperature of the feed water, reduce the temperature difference between the boiler water and the feed water, and reduce the thermal efficiency of the boiler feed water. National regulations: where the temperature of the boiler exhaust gas is less than 250 tons, the temperature of the boiler exhaust gas is less than 4 tons per hour. No more than 200 ℃. ≥10 tons / hour boiler exhaust temperature is not more than 160 ℃, otherwise economizer should be installed. The article is provided by the boiler maintenance for you!
