Today, there are two main types of green boilers used in different industries: biomass boilers and condensing boilers. Each of these operates in completely different ways to reduce your carbon footprint.
Biomass Boilers
Biomass boilers operate by burning wood and other renewable organic materials to produce heat. There are automatic biomass boilers that control the amount of air and fuel that is used, making them even more efficient. To keep this boiler running, owners will need ample ...
Agglomeration problem mainly occurs on the fireside in the fluidized bed boilers. Agglomeration is basically the ash-related problem of biomass-fired boilers. Ashes which are formed from high-sulfur and low-ash fuel agglomerate if they are prone to sulfating condition for long time.
A boiler economizer (also known as an economizer) are mechanical devices intended to reduce energy consumption or perform a useful function such as preheating a fluid. A boiler economizer is essentially a heat exchanger that makes a system more energy efficient by taking enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler – hence recovering more useful enthalpy and improving the steam boiler’s efficiency.
Steam boilers use a contained heat system to generate steam. The steam travels through pipes in the building’s walls where they emerge at radiators in heating systems. The radiators warm from the steam’s heat. As the steam gives off its heat, it condenses back to liquid water and returns to the tank. A boiler system of this type that does not allow outside water sources is a closed system and is highly efficient for using all the condensed water. An open network may be required in operations where the steam or water gets contaminated in such a way that it cannot return to the boiler for reuse.
Low-pressure boilers operate at a lower pressure and reach lower temperatures than high-pressure steam boilers. Water in low-pressure boilers is not heated beyond 250ºF, and the steam pressure does not exceed 15 psi (pounds per square inch).
If the impurities in the boiler feedwater are not dealt with properly, carryover of boiler water into the steam system can occur.
Carryover can be caused by two factors:
Three-pass steam boilers are so-called because the combustion gases that are produced inside them in the burner go round a circuit that has three parts before leaving it:
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.
