The pollution discharge of the biomass-fired boiler is less than the coal-fired boiler. It is also necessary to deal with the exhaust gas of the biomass-fired boiler to meet the national standards before boiler ignition and operation.
High exhaust temperature in a biomass-fired boiler can be caused by several factors, including:
1. Insufficient air supply: If there is not enough air supplied to the combustion chamber, the fuel may not burn completely, resulting in high exhaust temperatures.
2. Excessive fuel supply: Excessive fuel supply can overload the boiler, causing incomplete combustion and high exhaust temperatures.
3. Improper combustion: Improper combustion can lead to incomplete fuel burning and high exhaust tempe...
The boiler system consists of boiler body, energy-saving equipment, instrument valves, water treatment and control system, and some will add economizer. Because many users don't know what the working principle of boiler economizer is, here ZOZEN Boiler will answer for you.
Working principle of boiler economizer
Boiler economizer, as its name implies, is a boiler device for saving energy, which is generally installed at the tail of boiler flue and used to recover the waste heat of high ...
Boiler economizer is a system component that many boilers must be equipped with, but users may not know its working principle or even the installation position of boiler economizer. Today, ZOZEN Boiler will give you a detailed introduction on the composition and working principle of boiler economizer.
Boiler economizer, as its name implies, is used to save fuel coal and belongs to an energy-saving device of boiler. Boiler economizer has a simple structure, which is mainly composed of st...
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.
Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
Agglomeration problem mainly occurs on the fireside in the fluidized bed boilers. Agglomeration is basically the ash-related problem of biomass-fired boilers. Ashes which are formed from high-sulfur and low-ash fuel agglomerate if they are prone to sulfating condition for long time.
