Boiler Types - Fire Tube Boilers. Fire tube boilers confine the combustion process and gases in tubes and water circulates around these tubes. Some fire tube boilers have turbulators inside of the tubes to cause turbulence of the flue gases. This increases the heat absorption into the water which makes the boiler more efficient.
The boiler is merely a heat exchanger device designed to absorb heat from combustion products and to transfer that heat into water. When excess air is added to the perfect, or stoichiometric, amount of air, obviously more mass is forced through the boiler.
Good combustion is very rapid, has a high flame temperature, and is very turbulent. Turbulence is a key factor in boiler furnace combustion. If the turbulence is high, the mixing of the oxygen and fuel will be good, therefore, combustion will occur very rapidly and the result will be a high flame temperature.

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler." Boilers that operate higher than 15 psig are called "high-pressure" boilers. A hot water boiler, strictly speaking, is not a boiler.
Nov 08, 2016 · The watertube boiler produces hot water or steam for industrial or commercial applications. Watertube types of boilers are extensively used for comfort heating applications. With this type of boiler, tubes house water and/or steam. At the same time, the combustion products are circulated through the tubes.
To overcome these difficulties a new coal combustion system is developed and is called as Fluidized Bed Combustion System, (FBCS). In this system any type of coal can be burnt efficiently in the temperature range of 900-1000°C. At these temperatures production of pollutant like NO x is less, and slag formation is almost nil.

Boiler Efficiency Improvement Steps: This heat can be utilized to preheat the air or water used in a boiler. The optimum ratio of fuel to air and keeping the excess air as low as possible keeping in mind the complete combustion of fuel can increase the furnace temperature thereby increasing the radiation heat. Reducing excess air by 5% can increase boiler efficiency by 1%.
Fire tubes boilers are also known as a smoke tube boiler. Water tube boiler: Water tube boilers are those boilers in which water flows through a number of tubes (called water tubes) and the hot gases produced by the combustion of fuel in the boiler furnace while on their way to chimney pass surrounding the tubes.
A boiler is a self-contained combustion system that heats water. The hot water or steam produced by a boiler is then used in heating systems. Although designs vary, a boiler has four main parts: the burner, the combustion chamber, the heat exchanger and the pluming apparatus. The burner initiates the combustion reaction within the boiler.

Another type of combustion is Rapid Combustion. Rapid energy needs external heat energy for the reaction to occur. The combustion produces a large amount of heat and light energy and does so rapidly. The combustion will carry on as long as the fuel is available. An example is when you light a candle.
There are two types of steam boilers. One is the fire tube, which is made from one combustion chamber and many tubes. The hot gases that are produced during the combustion process pass from inside the tubes and make a heat transfer with the water that is on the outside of the tubes. The other type is a water tube steam boiler.
Energy. The source of heat for a boiler is combustion of any of several fuels, such as wood, coal, oil, or natural gas. Electric steam boilers use resistance- or immersion-type heating elements.
