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...
The fuels of ZOZEN WNS gas/ oil fired boiler are mainly oil and gas. Oil and gas fuel are supplied to burner by piping conveying.
Oil fuel supply system mainly includes: oil storage tank, daily-used oil tank, oil filling pump and oil filling pipelines.
Oil storage tank: This is used to store oil for boiler combustion. Small capacity oil storage tank usually adopts buried layout and buried tank should be reliably fixed and be guaranteed not be floated by surface water. Oil tank that volume is m...
Industry boiler usually adopts ion-exchange method for water softening, dealkalization and desalination. There are two kinds of water softener- automatic operation and manual operation.
Water softener specification, resin loading capacity and salt consumption are directly related to raw water hardness, so it is crucial to select correct water softener according to raw water situation.
According to its working control method, full-automatic water solener could be divided in two typ...
In recent years, the contradiction between energy supply and demand and environmental pollution has become increasingly prominent, and all small coal-fired boilers with backward technology have been transformed into natural gas boilers with clean energy. The flameout of natural gas boiler is one of the common faults of boiler, so how to deal with the flameout problem?
Trouble shooting of natural gas ignition and flameout in boiler
It is necessary to check the causes of the natural gas ignition...
The principle of boiler heating is a kind of thermal equipment that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container, so that the water can reach the required temperature or steam with a certain pressure. After the water enters the gas boiler, the heated surface of the gas boiler transfers the absorbed heat to the water in the steam-water system, so that the water is heated into hot water with a certain tempe...
Gas-fired boiler uses natural gas, biogas, coke oven gas, etc. as fuel, it has high combustion efficiency, and its emissions are commonly used energy equipment in food, chemical, building materials, medicine and other industries. The rated output of gas-fired boiler is generally used to describe the heating capacity of boiler. Here, ZOZEN Boiler will take you to learn how to choose the rated output of gas-fired boiler.
Rated output of gas-fired boiler
The rated output of the gas boiler refers ...
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...
