The coal-fired boiler uses coal as fuel. The consumption of coal is a key factor to measure the efficiency of boilers. Under the same condition, the coal-fired boiler with less coal consumption can save more costs for enterprises. However, the coal consumption of coal-fired boilers is related to many factors, such as the efficiency of the boiler, the calorific value of fuel coal and the degree of coal combustion.
Here, we'll address four of the key mechanical benefits that serpentine coil heaters have to offer.
1. Coil Replacement
Coil replacement in serpentine industrial coil heaters is notably easier than that in helical coil heaters. With serpentine coil thermal oil heaters, you can replace one tube at a time instead of replacing the entire coil. This can save you thousands of dollars on the cost of purchasing a new helical coil in its entirety. Because the coil replacement can be taken care of quickly, you'll also save hundreds of thousands of dollars by avoiding excess facility downtime.
The change of heating pressure of natural gas will affect the normal operation of the boiler, resulting in anoxic combustion, deflagration, peroxide combustion, tempering and other phenomena. Then, what factors are generally related to the gas supply pressure of natural gas boilers, and how much should it be?
Gas supply pressure of boiler
The natural gas supply pressure of the boiler is mainly related to the tonnage of the boiler, and its general principle is:
If it is a gas boiler wi...
Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
The main purpose of boiler acid washing is to remove iron oxide, copper scale, iron scale and other impurities in the evaporation heating surface of the boiler, and also to eliminate silicon dioxide and scale.
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.
The natural gas fired boilers occupy a large proportion of boilers for the industrial and civil uses. They have low energy consumption and can reach the environmental protection standards.
The explosion-proof door of the gas-fired boiler is opened or broken when the combustible gas explosion suddenly increases the pressure, it then releases high-pressure gas to reduce the damage to the gas-fired boiler body and also ensure
The function of the gas-fired boiler explosion-proof door is usually reflected when the gas-fired boiler is ignited or running due to improper operation. For instance, the furnace is not purged before ignition, the furnace is still not purged even the ignition cannot successfully be lit, the nozzle is leaking, the fuel is not completely burned, and extinguished failure to cut off fuel quickly, etc. all of them may cause the furnace and tail flue to explode. Installing explosion-proof door for gas-fired boiler is to release the pressure to avoid the accident from expanding and also to ensure the safety of the industrial steam boiler when a slight explosion occurs in the furnace or flue.
