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 construction and working principle of the boiler economizer is simple. At the bottom part, it has a horizontal inlet pipe through which we feed water with normal temperature to the economizer. There is another horizontal pipe fitted at the top of the economizer.
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
When they reach a certain size, industrial steam boilers are installed in a boiler room which is necessary to ensure safety while they are operating as pressure equipment, in accordance with local regulations.
Whether it's an industrial hot water boiler or an industrial steam boiler, they all depend on fuel to run. The process of heating is initiated as the burner heats or eventually evaporates the water inside of it. It's actually transported via intricate pipe systems.
Steam boilers transport through the pressure created by the process, while hot water boilers use pumps to move heat throughout the system. Eventually the condensed steam or cooled water returns back through the pipes to the boiler system, so the heating process can be initiated again.
As the boiler creates heat energy, a byproduct of the process — flue gases — are exited through a chimney system. Because of this, regulating the industrial boiler emissions is a very serious issue.
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
According to the power of water or steam circulation, boilers can be divided into natural circulation boilers, forced circulation boilers, once-through boilers and combined circulation boilers.
Boiler is a piece of equipment with large energy consumption. Therefore, both boiler manufacturers and purchasers regard energy conservation as an important indicator of boiler performance. The daily energy-saving measures of the natural gas fired boiler are mainly as follows.
