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%.
Package boiler is a boiler that had been fabricated and available as a complete package. The entire pressure parts have been assembled in the workshop and ready to be sent to the field or site where power plant is located. On the field/site requires only connection and integration of course work in electrical connections, water pipes, steam pipes and fuel piping system to operate. Package boiler is one of classification of boiler based on erection. Design package boilers in general are the type of Fire Tube Boiler and have made up shell and tubes. This type has high heat transfer both radiation and convection.
If your boiler equipment freezes, you can expect a shutdown and significant loss of productivity. Winter can be tough on your boiler system. The experts at ZOZEN Boiler weigh in on what you can do to prevent your industrial boiler from freezing up.
All boilers, whether hot water or steam, depend on fuel to run. The heating process is initiated when the burner heats or evaporates the water inside it, which is ultimately transported via pipe systems. Hot water boilers rely on pumps to move the heat through the system, while steam boilers are transported with the pressure generated in the heating process. Eventually, cooled water or condensed steam is returned back through the pipes to the boiler system so that it can be heated once again. While the boiler is generating energy in the form of heat, flue gases, a byproduct of this process, are removed through a chimney system - which is why regulating the emissions of industrial boilers is taken very seriously.
Here are some common issues that could cause your industrial boiler to misbehave.
1. Burner Not Functioning Correctly.
If the boiler burner fails or is faulty, then your boiler is not going to be able to generate heat efficiently, or in the worst case not at all . As industrial boilers are in almost constant use they are built to be very robust and last for decades, nevertheless they can still have problems with broken burners from time to time. Burner pumps, heads and nozzles can all cause problems but a swift replacement should limit your down time.
The service life of your industrial boiler is 15 years. Of course, there are a number of factors that may force you to replace your boiler before it reaches the 15-year mark. If there are obvious signs of wear and tear, you may not want to push the boiler much longer.
Boilers are often distinguished by fuels that power them. The kind of fuel makes an essential difference in operating costs and environmental impact, so it’s important to learn about the various types of boiler fuel.
Coal, is a common boiler fuel. It dominates the global energy arena due to its abundance, affordability and wide distribution across the world. The most commonly used coal fuels include anthracite, bituminous coal, sub-bituminous coal, lignite and peat.
