Thermal power generation is an important way to generate electricity. Coal is an important strategic resource in thermal power generation, and it is also one of the raw materials. Its process is actually very simple, that is, by burning coal, the hot water heated after burning is turned into water vapor, which drives the generator and is finally converted into electric energy. Then, some users ask how much electricity a ton of steam from a medium-temperature and medium-pressure boiler can genera...
Tap water or water with a lot of impurities will cause the magnesium ions and calcium ions in the water to form some white precipitates when heated at high temperature, causing scaling problems and reducing the heat transfer efficiency of the boiler. Boiler operation safety brings hidden dangers, even shutdown.
The specific reason why softened water must be used in hot-water boilers is that it will not produce scale in the process of use, so that potential safety hazards of boilers can ...
As a clean fuel, natural gas has much lower sulfur content and nitrogen content than coal, and there is no ash in the fuel, and the flue gas produced after combustion is almost smoke-free. Therefore, a nationwide upsurge of coal to gas has been set off.
However, there are some problems in the process of gas boiler operation, among which the hardness, harm and treatment of gas boiler flue gas condensate are prominent.
When the boiler flue gas temperature is lower than the dew po...
The main working principle of industry is a kind of heating equipment which uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the medium in the container, so that the medium can reach the required temperature, and then it can be transported to the heating process for heat exchange. According to different media, boilers can be divided into many types.
Types of boiler heating medium
1. Steam, steam boiler and superheated steam b...
Industry boiler is an important thermal power device, which is widely used in factory power, building heating, people's life and other aspects, with a large demand and a wide variety. According to the different flue gas passes, gas-fired boilers are divided into two-pass and three-pass boiler structures. Here, ZOZEN Boiler focuses on the structure and process principle of the common three-pass boiler.
The first pass: after the fuel is atomized by the burner, the formed torch is filled i...
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 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...
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...
