In the realm of industrial boilers, economizers play a pivotal role in enhancing efficiency and reducing fuel consumption. Essentially, a boiler economizer captures waste heat from boiler flue gases and uses it to preheat the feedwater before it enters the boiler. This process significantly improves the overall efficiency of the boiler system by reducing the need for the boiler to heat the water from a lower temperature. But, how long can one expect an economizer to last?

(1)Ensure normal and stable steam pressure, steam temperature and evaporation.
(2)Avoid coking and burner damage; Ensure the safety of the operation of the superheater; Reduce pollution of combustion.
(3)Make the operation achieve the highest economy.
Serious coal leakages in the fire grate of coal-fired boilers can be caused by several factors, each impacting the efficiency and safety of the boiler operation. Understanding and addressing these issues is crucial for maintaining optimal performance. Here are some common causes:
Wear and Tear: Over time, the fire grate components can wear down due to the constant exposure to high temperatures and the abrasive nature of coal. This wear can create gaps through which coal can fall.
Improper Grat...
Proper shutdown procedures are crucial for ensuring the safe and efficient operation of a coal-fired steam boiler. The following steps should be followed when shutting down a coal-fired steam boiler:
1. Reduce the load: Before shutting down the boiler, the load should be reduced to its minimum level. This will help to prevent sudden drops in pressure and temperature, which could cause damage to the boiler and its components.
2. Shut off the fuel supply: The fuel supply to the boiler should be ...
The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
Question details (Performance) :
1. The vibrating coal grate stops running totally or intermittently.
2. The current of vibrating coal grate motor rises abnormally.
3. The safety clutch of transmission machine of grate or safety pin is broken.
Answer: cause of the problem:
Boiler’s vibrating coal grate is a rotating combustion equipment, due to the bad working conditions, stuck stalling is easily happened and grate failure happens in daily application and ...
Commonly used dust removal equipment of SZL boiler includes multi-tube dust collector, wet scrapper and bag filter.
1. Multi-tube dust collector: XTD type vertical ceramic multi-tube dust collector has the advantages of wear-resistance, high temperature resistance, corrosion resistance, low cost, etc. Its collection efficiency is not less than 95%, resistance is not higher than 900Pa and mainly removed dust granularity is greater than 20um.
Design, manufacture and acceptance of multi-t...
There are many factors that affect the operating cost of the boiler, among which the insufficient combustion of the coal-fired boiler directly leads to an increase in the cost of the boiler. Therefore, users should adjust in time during daily operation and use to avoid insufficient combustion of coal-fired boilers.
Causes and treatment of insufficient combustion of coal-fired boiler
1, Insufficient air volume; Need to increase the air intake,
2, poor ventilation, insufficient oxygen supply, s...
