EPA has promulgated national emission standards for hazardous air pollutants from three major source categories: Industrial boilers, commercial and institutional boilers, and process heaters. The final emission standards for control of mercury, hydrogen chloride, particulate matter (as a surrogate for non-mercury metals), and carbon monoxide (as a surrogate for organic hazardous emissions) from coal-fired, biomass-fired, and liquid-fired major source boilers are based on the maximum achievable control technology. In addition, all major source boilers and process heaters are subject to a work practice standard to periodically conduct tune-ups of the boiler or process heater.
The primary use of steam boiler in tire manufacturing is the vulcanizing process — the curing of the rubber needs steam to provide heat energy. Curing is a process in which chemical or physical action takes place for harder, tougher and more stable linkage.
As we know tires are the most important part of our vehicle because in all the parts of vehicle tires only remain in contact with the earth hence tires carry all the load of vehicle and passengers.
Vulcanization is a p...
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:
