Package boilers are generally shell type with fire tube design so as to achieve high heat transfer rates The packaged boiler is so-called because it comes as a complete package. Once delivered to the site, it requires only the steam, water pipework, fuel supply, and electrical connections to be made for it to become operational.
The flame tube, internal water-flushed rear flue gas reversing chamber, first smoke tube and second smoke tube are all arranged for optimum flow within the cylindrical pressure vessel. The main areas of use of the UT-H hot water boiler are local and district heating generation, all sectors of business, the processing industry, heat suppliers and public facilities.

In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion gases. The firebox is surrounded by a cooling jacket of water connected to the long, cylindrical boiler shell. The hot gases are directed along a series of fire tubes, or flues, that penetrate the boiler and heat the water thereby generating saturated ("wet") steam.
Cornish boiler is an internally fired horizontal fire tube boiler. It is a most famous type of fire tube boiler. It has a cylindrical shell that is installed in the horizontal direction. This shell has a 1.25 m to 1.7 m diameter while 4 m to 7 m length. In 1812, Richard Trevithick designed the first Cornish boiler.
Steam boiler definition types fire tube boiler By Emoscopes CC BY SA-2.5 via Wikimedia Commons The tubes are submerged into the water inside the shell. Heat is transferred from hot tubes to the surrounding water through the walls of the tubes.
Internal Furnace Smoke Tube Boiler: On the basis of Heat Transfer methods between the flue gases and water, most boilers can be divided into two basic parts: Furnace: Where the radiation heat transfer dominate. Tubes: Where the convection heat transfer is prominent. Thermodyne's Intech models are Shell and Tube type, which include furnace and

Combitherm boiler or is known among others as Combi boiler is a unique water cum smoke tube type design. It is the combination of both Water Tube Boiler and Smoke Tube Boiler where some tubes form the enclosed part of the external furnace in which water flows and rest of the tubes are placed in a shell in which flue gases flow.
This is a vertical design shell and tube type boiler suitable for various fuels like oil, wood, coal, rice husk, briquettes etc. or a combination of these fuels. The furnace for solid fuels like wood, coal, rice husk etc. is constructed below and the boiler is placed vertically above it.
2016/5/13 · Smoke tube boiler and water tube boiler are the main types of industrial boiler in global market. They are differ from not only structure, but also usage. Smoke tube boiler Smoke tube boiler, as its name suggests, of which smoke or heat flowing through boiler tubes
Coil Type Boiler Smoke Tube Boiler Overall Steam : Fuel Efficiency Low, typically 75% as found by actual trials As high as 89% on NCV Steam space A coil type boiler is water tube design, the water travels through the coil and is surrounded with flue gases. The
Shellmax is a packaged, three-pass smoke tube, with a fully wet back boiler. Shellmax comes in two series – SMDL for burning light oils & gas and SMDH for burning heavy oils. It can also be customized to a completely skid mounted unit on customer demand.
Fire tube boilers, also known as smoke tube boilers, are the most common type of industrial boiler employed today. Compared to water tube boilers, they are much more suitable for smaller plant applications because they can better cope with sudden high demand steam fluctuations.
2013/3/12 · 1) These types of boilers have light weight construction. 2) Efficiency compared of the smoke tube boilers is much higher and those can be used to generate the high pressure steam. 3) Efficiency of combustion in this type of boiler is always good. 4) Thermal stresses are less as the water circulation is very good inside the tubes.
Coil type steam boilers are designed to operate on a wide range of liquid and gaseous fuels including diesel fuel, heavy oil, light oil, gas, etc. Smoke Type Industrial Boilers Smoke Tube Steam Boiler consists of the main shell with tube sheet welded with smoke tube and integral furnace, where flue gas travels through a furnace and smoke tube to I.D. fan and chimney, where water heated outside
Salient Features of the RS - Oil/Gas Fired, 3 Pass, Shell Type, Flue Tube Steam Boilers are. Robust design, with ample evaporation surface for dry steam. Easy to maintain and service. Smoke tubes are easily accessible for maintenance. Ideal choice for users with high steam demand.
Types of Marine Boilers: #1. Smoke Tube Boiler. As the name suggests, the hot smoke generated in the boiler furnace passes through several tubes surrounded by water in the boiler drum. The heat of smoke in the tubes generates steam. Smoking tube boilers are …
Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as 'fire tube' or 'smoke tube' boilers because the products of combustion pass through the boiler tubes, which …
A smoke tube boiler (It is also called a fire tube boiler) is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
Shellmax is a packaged, three-pass smoke tube, with fully wet back boiler, when fitted with a special burner, these boilers are ideal for burning waste gases like biogas from decomposition of organic matter in distilleries, corex gas from the steel manufacturing process and liquid fuels.
