Water Tube Boiler
The water tube boiler is one type of boiler, and the main function of this boiler is the water in the tube will be heated to generate the vapor. The main benefits of this boiler are, used in huge thermal power-stations. By using a number of water tubes a big heating surface can be attained. The water movement is much faster, so the heat transfer rate is very high which consequences to high-efficiency. This type of boilers requires fresh water as well as water treatment plants to maintain the necessary quality of water tube boiler.
Fire Tube Boiler
This type of boiler can be built with a number of tubes for supplying the hot gases. These tubes are absorbed into water in a closed container. Actually, this type of boiler consists of a single closed container to pass the hot tubes. These tubes are heated up the water to convert into vapor and the vapor remains in the similar container. When both the water as well as vapor is in a similar container, then a fire-tube boiler cannot generate vapor at high force. In general, it can generate the utmost 17.5 kg/cm2 & with a 9 Metric Ton capacity of steam for each hour.
Package Boiler
A packaged boiler is a separate application which is used to get the energy from an incorporated burner with fueled by oil or gas. This type of boiler is proficient in producing huge steam output at a high-pressure as well as high-temperature. This boiler operates variable loads which have a small start-up or response time. The applications of this boiler mainly include process steam for industrial, chemical or used as power generator with a steam turbine. The package boiler can be used as a peak-load boiler because of an addition to another power that kicks in while other supplies not succeed.
Stoker Fired Boiler
The stoker fired boiler is most capable in common range and cogeneration systems in sugar factories. These boilers have membrane design and operate completely automatic. These Boilers have intrinsic features for the operation of trouble-free and high-thermal efficiency. These are classified based on the technique of supply fuel to the boiler & with the grate type. The stoker-fired boilers are classified into two types namely chain-gate or traveling grate stoker and spreader stoker.
