Water treatment outside the boiler
Before entering the boiler, raw water is treated with water treatment equipment to remove impurities such as hardness, salinity, dissolved oxygen, etc., so that the feed water can meet the water quality requirements specified by steam boiler. Common water treatment equipment includes sodium ion exchange water softening equipment, ion exchange desalination equipment, reverse osmosis water purification equipment and thermal oxygen removal equipment.

The quality of the water used to produce the steam in the boiler will have a profound effect on meeting the objectives such as safe operation, maximum combustion and heat transfer efficiency, minimum maintenance and long working life.
Specific performance:Low level alarm of expansion tank.Answer:Cause of failure:The pipeline system (including heater) has not been replenished in time after oil leakage or degassing. Troubleshooting:Eliminate system defects and add oil.
Circulating fluidized bed boiler is a specific type of boilers, and compared with the other boilers, it has certain advantages, which are: it has great improvement in combustion technology, which can improve the boiler combustion quality and combustion effect, and in turn, to improve the boiler effect. This is achieved because two return feeders are used in this type of boiler to allow the fuel to form a circulation loop between the furnace and the return feeder.
In order to improve the combustion efficiency of the boiler, in a large boiler, the combustion air is not supplied all at once, but is supplied in two times, one is supplied with the fuel that controls the rate of combustion as well as the amount of fuel that can be burned,and the other is directly supplied to the combustion process that that improves combustion efficiency. The primary air rate of the boiler refers to the proportion of the primary air. If the total air volume is 100% and the primary air rate is 70%, the secondary air rate is 30%.
As a kind of common heating equipment, boiler has many functions. Textile, energy, building materials, construction, chemistry and metallurgy are the main markets of boiler. According to different classification methods, there are many kinds of boilers, but not all of them are special equipment and are subject to supervision. Therefore, users often ask how many tons of boilers are special equipment.

Industrial boilers are important thermal energy supply equipment in the national economy. Electric power, machinery, metallurgy, chemical industry, textile, paper, food and other industries, as well as industrial and civil heating all require boilers to supply a large amount of thermal energy. Here, ZOZEN Boiler summarizes the heating methods and principles of industrial boilers, hoping to help everyone.
Generally speaking, the heating methods of industrial boilers mainly include conduction, co...
