Boilers, Burners, and Boiler Room Equipment: Understanding Combustion Systems
A burner is a form of furnace, in which the source of energy and heat is through combustion of fuel – either liquid or gas that is heated to high temperatures. The type of furnace is achieved by heating the space with an outside air source or fuel burner, and then turning the heated air into steam. The outside of the room gets hot due to the steam, while the inside stays warmbecause the fuel is either liquid or gas. to heat the inside through chemical reactions. In the majority of cases, this type of boiler is paired with an air compressor, which is used to push outside the water and gases into the room to maintain it at the same temperature.
Burner Combustion Systems provides boiler burners and combustion systems. Burners are typically paired with othertypes of furnaces to allow them to provide more efficient heating. Other furnaces can utilize oil, gas, or coal, in addition to the heat produced by the burner. Some boilers utilize an electric spark plug to ignite the gaseous fuel. Others use a venturi to let some of the fuel escapeso that the fuel burns more quickly before it`s consumed. Combination boilers powered by both gas and electricity are the most popular.
Burner Combustion Systems is a unique sales and service company for commercial and industrial boilers, burners and all other boiler room equipment. Burner Combustion Systems offers sales, service, and boiler rentals for on-demand modular steam systems and cutting edge burners and burner management systems from many manufacturers.
To understand the connection between the burner and its componentsit is helpful to understand the basics of the burner combustion process itself. The actual combustion of gas or liquid occurs at the end a passage through a pipe. This flue gas contains various components, but its primary purpose is to serve as a conduit for gases that are combustible to flow through until they reach the end of the burner. The combustion chamber is the place where the fuel is ignited. As the combustion occurs, gaseous vapors are released into the atmosphere and become part of the air we breathe.
There are two main types of burner arrangement: top-down or bottom-up. Top-down designs include the flame that comes from the burner at the edges. A bottom-up arrangement permits the flame to beplaced closer to the middle of theburner stack, which makes it more likely for the flame to catch fire and initiate the process of combustion. Both types of burners may be powered by one or more sources of electrical power, including steam engines, gasoline engines, or diesel engines.
A variety of design features are common to contemporary steam boilers. These characteristics include bottom flues to ensure the highest efficiency, a closed vent boiler room, variable temperature and volume control, and direct feed burners with variable feed rates. There are many ways to build steam boilers in order to achieve the desired outcome. Some boilers can be constructed to generate direct heat. The hot water flows through the room by means of a pipe and not vented out.
Variable firing rates are another characteristic of modern boilers. Variable firing rates control the amount of combustion that plays a part in the heating process of the boiler. When the combustion occurs at a high rate, the hot water temperature within the boiler becomes excessively high, and the boiler may overheat. If this happens, the boiler will shut down until it has cooled down enough to allow it to return its heating output to an acceptable level. A turbo variable firing unit is often used to create an adjustable firing rate system. Variable valve arrangements are available on a few of the more expensive steam boilers. This allows the temperature of water that is pumped into the boiler to be controlled.
