The ignition of industrial coal-fired boiler needs to be operated steps by steps, and the ignition operation is different according to the specific model of industrial coal-fired boiler. Grates of industrial coal-fired boilers are usually divided into manual grates and mechanical grates. Here, according to the different grates, the correct ignition steps of industrial coal-fired boilers are introduced in detail.
In the industrial boiler industry, it is generally divided into four grades: A, B, C and D according to the production qualification license grade, among which, when purchasing boilers, users often consider Grade A boiler manufacturers. What is a grade A boiler?
The so-called tower boiler refers to a boiler with a furnace at the lower part and a convection flue at the upper part. The features of domestic tower and tanks include the following aspects.
In the process of the development of national economy, the importance of boilers is self-evident. The so-called boiler is a device that uses the heat energy released by fuel incineration to heat water or other media, so as to obtain steam, hot water or other media with specific parameters (temperature and pressure).
Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
In the dairy industry, an efficient steam boiler is quite necessary to the dairy production process. The dairy steam boiler is critical milk processing equipment to transfer the raw milk to the high-quality of dairy products. Therefore, choosing a good dairy steam boiler is one of the most important decisions a dairy plant must make.
When you choose the dairy steam boiler, the first thing you shall pay attention to is the boiler shall meet the fluctuating load demands. Second, the boile...
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
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.
