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.

When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
In addition to quality, price is also an aspect that most corporate users are very concerned about when they purchase the gas-fired thermal oil heater, so what is the price of a set of high-quality gas-fired thermal oil heater?
1. The types and parameters of thermal oil heater, such as rated thermal power, rated working temperature, etc.
Rated thermal power: heat output per unit time. Thermal oil heaters with different heat output per unit time have different prices.
Rated wor...
A steam generator is a mechanical equipment that uses the heat energy of fuel or other energy resources to heat water into hot water or steam. It belongs to small equipment and is a kind of steam boiler. According to Boiler Safety Technical Inspection Regulations, a boiler whose water volume exceeds 30 litres belongs to pressure container, national special equipment. There is no need of water storage in the internal structure of modular steam generator concurrent pipeline and the water volume is...
When we talk about CFBC in the area of industrial boiler, it usually means the circulating fluidized bed combustion. The circulating fluidized bed (CFB) is a type of fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion.
