Jul 12, 2016 · The most common fuel types used in industrial boiler systems are as follows: Coal Most industrial coal-fired boilers run on crushed coal, which burns more efficiently than large coal clumps. Gas and Oil Gas-fired boilers operate using natural gas, most often a mix of methane, ethane, butane,Online chat
Large steam users are better suited for the water-tube design. The industrial water-tube boiler typically produces steam or hot water primarily for industrial process applications, and is used less frequently for heating applications. The best gauge of which design to consider can be found in the duty in which the boiler is to perform.Online chat
Shell and tube boilers. Shell and tube boilers are also referred to as fire tube or smoke tube boilers. Fire tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. Fire tube boilers, typically have a lower initial cost, are more fuel efficient and easier to operate.Online chat
Combustion efficiency also varies with the fuel being burnt. Combustion efficiency is higher for liquid and gaseous fuels than for solid fuels. Thermal Efficiency. The thermal efficiency of a boiler specifies the effectiveness of the heat exchanger of the boiler which actually transfers the heat energy from fireside to water side.Online chat
The Solid Fuel Water Tube Boiler, offered by us, is designed with water tube to operate even on fuel that has high fouling tendency.Our Solid Fuel Water Tube Boiler can be used for generating saturated steam as well as superheated steam.Online chat
Boiler efficiency (%) = 100 (heat exported by the fluid (water, steam ..) / heat provided by the fuel) (1) Heat Exported from the Boiler to the Fluid. If a fluid like water is used to transfer heat from the boiler - the heat transfer can be expressed as: q = (m / t) c p dT (2) where. q = heat transfer (kJ/s, kW) m / t = mass flow (kg/s)Online chat
The furnace and the banks of tubes are used to transfer heat to the water. Combustion occurs within the furnace and the flue gases are routed through the tubes to the stack outlet. Firetube boilers are available in two, three and four pass designs. A single pass is defined as the area where combustion gases travel the length of the boiler.Online chat
Therefore, these fuels cannot be used in boilers of shell type with internal flues. Although the fire tube boilers possess a steam reservoir of large size, they are less efficient. On the other hand, water tube boilers are more efficient, but they are complicated. Again, they cannot store a large amount of steam.Online chat
Water tube boilers are the most widely used boilers. These type has replaced many boilers, including the fire tube type, mainly because of the following reasons : The weight of the water tube boiler is much less than any type of boiler of equivalent size. Steam raising and steam generation process is much fasterOnline chat
Boiler is a device used to generate steam at a desired pressure and temperature by transferring heat energy produced by burning fuel to water to change it to steam. Normally boiler is a combination of apparatus used for producing, furnishing or recovering heat together with the apparatus for transferring the heat so made available to the fluid being heated and vaporized.Online chat
