The boiler economizer is a device installed at the lower part of the flue at the tail of the boiler to recover the waste heat of the exhaust gas. It absorbs the heat of the high-temperature flue gas to heat the boiler feed water, reduces the temperature of the exhaust gas of the boiler, saves energy and improves the thermal efficiency of the boiler. Therefore, when using boilers, it is very important to master the correct treatment method of boiler economizer tube burst.
The first reason is unreasonable structural design.
In the operation of chain grate boiler, uneven distribution of short coal seams in grate, improper adjustment of coal feeder, unreasonable control of coal seams and poor regulation performance of air supply volume in air chamber will all lead to insufficient burning of coal.
The second reason is unreasonable setting of secondary air.
If the primary wind speed is too high, the air volume is too large, and the air rate is too large, the pulver...
Different boiler types have different weights. The traditional four-ton coal-fired horizontal boiler in China is about 25~30 tons.
ZOZEN Boiler has two series of coal-fired horizontal boilers, which are DZL series and SZL series. The DZL series with the capacity of 4 tons weighs 25 tons, and the SZL series with the capacity of 4 tons weighs 32 tons.

Recently, some users have come to consult how to solve the ash leakage at the expansion joint of boiler flue outlet. ZOZEN Boiler suggested that in case of ash leakage from the expansion joint at the boiler flue outlet, please contact the professional industrial boiler manufacturer.
To buy dust removers for coal-fired boiler with good cost performance, we should first know more about the manufacturer, quotation and market. After all, a good vendor can bring more help to customers. Therefore, determining the sales manufacturer will be the focus of purchasing coal-fired boiler dust collectors. Coal-fired dust remover has high efficiency and will have more outstanding performance in use. Of course, when selecting products, we should know the quality of coal-fired boiler dust removers, so as to choose equipment with reasonable price and stable performance.
The price difference of coal-fired boiler dust remover is mainly due to the different specifications and models.
Chain grate has certain selectivity for coal types, and soft coal with volatile content above 15%, ash melting point above 1250℃, moderate particle size and calorific value above 18800~21000kJ/kg is more suitable.
The type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
