Coil Type Boiler: Revosteam
Revosteam, Coil Type Boiler, is a unique water tube coil type boiler in which water flows inside the tube.
Revosteam is mostly oil-fired or gas fired boilers which include burner assembly to fire oil or gas.
It incorporates the unique principle of combustion known as “Reverse Flow”.
Reverse flow means that flue gas reverses its path when they hit the bottom of the shell.
This flow of flue gases enhances the combustion efficiency and also allows a high rate of heat release to the surrounding water coil.
It can be offered in both IBR and Non-IBR designs
Revosteam Construction
A Water tube Coil type boiler comprises a jacketed MS shell housing a helical coil. The combustion air is forced through the jacketed shell by means of a centrifugal blower thereby getting it pre-heated.
For the Revosteam Boilers, in the coil, the flame travels downwards 1st because of vertical fit-up of the burner inside the coil then the flue gases reverse upwards in the same coil thereby giving 2 passes in the same radiant zone.
This ensures maximum radiation heat transfer to water through tubes. After reversing its path, flue gases reach the top of the shell and from there, the flue gases pass between the inner shell and the coil which makes the 3rd pass of flue gases.
The high velocity of gases in this region allows heat exchange between the gases and water through convective heat transfer.
After completing 3 passes in the boiler, flue gases then enter the economizer. Economiser which is kept on the same skid as a boiler is a shell and tube design. In this flue gases are on the tube side while water is on the shell side.
Economizer is generally given to pre-heat water entering the boiler. Along with other accessories, an optimizer is also installed on a skid in series with the boiler and an economizer so as to maintain the inlet water temperature to the boiler. The inner shell separates the flue gases & outer shell.
Ceramic blanket is applied on the inner side of the outer shell to reduce the heat transfer to the ambient and the surface temperature of the outer shell in the Revosteam Boiler.
Coil type Boiler Advantages:
- Fully Automatic unit
- Unique four pass design
- High efficiency and low running cost
- Minimum site-work, low installation costs
- Instant streaming within five minutes of a cold start
- Built-in economiser increases the operating efficiency
- Fail-safe design and dependable operating instruments
Revosteam’s Capacity
Revosteam- Water Tube Coil Type Boiler is available in capacities from 1 hundred Kg/hr to 12 hundred Kg/hr.
We, at Thermodyne engineering Systems, design and manufacture the Revosteam Boilers for both Liquid/Gas Fired Fuels. And the best part is that complete fit-up of mountings, fittings and accessories is checked, inspected which is further followed by a test run of the Boiler to ensure maximum customer satisfaction during future boiler operation.

Water Tube Coil Type Boiler RevoSteam FAQ
A coil type boiler is a type of boiler that uses a coil of pipe to heat water. The coil is heated by a flame or other heat source, and the hot water is then circulated through a system to provide heat.
A non-IBR boiler is a type of boiler that does not have an internal combustion chamber. Instead, the fire is created outside of the boiler and the heat is transferred to the water through a heat exchanger.
A coil tube boiler is a type of boiler that uses a coil of pipe to heat water. The coil is surrounded by tubes that carry hot water or steam. The heat from the tubes is transferred to the coil, which then heats the water inside.
A coil type steam boiler is a type of boiler that produces steam by heating water in a coil. The coil is heated by a flame or other heat source, and the hot water vaporizes to form steam.
A water tube steam boiler is a type of boiler that produces steam by heating water in tubes. The tubes are surrounded by a firebox, and the heat from the firebox is transferred to the tubes, which then heat the water inside.
Coil type boilers are relatively inexpensive to purchase and install. They are also easy to maintain and repair.
Coil type boilers can be less efficient than other types of boilers. They can also be more difficult to clean.
Non-IBR boilers are more efficient than IBR boilers. They are also less likely to experience water hammer.
Non-IBR boilers can be more expensive to purchase and install. They are also more difficult to maintain and repair.
Coil type boilers should be installed and operated by qualified professionals. They should also be inspected regularly for leaks and other problems.
