In lieu of water or water glycol a molten salt is used.
Indirect fired water bath heater.
Grand prix engg pvt ltd faridabad grand prix engineering pvt.
The main application for indirect fired water bath heaters is to heat high pressure gas prior to pressure reduction.
Ltd plot no 82 sector 25 faridabad haryana faridabad 121004 dist.
The process coils and the fire tubes are immersed in a water or liquid bath.
Gas pipe inside the heater.
Burners low nox or conventional mono fuel or bi fuel.
All our products are manufactured using excellent quality metal employing latest machinery tools and advanced technology under the guidance of our reliable engineers.
Indirect heaters works by submersing a fluid or gas carrying process coil into a heated bath solution which indirectly heats the coil allowing for safe efficient uniform heating of oil and other fluids.
Tube bundle or coil.
4 how water bath heaters work.
Common bath mediums include water water glycol and hot oil.
Indirect water bath heater operation.
Delham heaters operate on an indirect heating basis which consists of a water bath with two high pressure inspiriting natural draft burners firing into immersion tubes.
Natural circulation or forced flow.
Gas fired water bath heaters are a type of indirect process heater designed to safely heat product without contaminating it.
As the unit is fired heat is transferred from the fire tube to the liquid bath and then to the process fluid.
Water bath heaters are indirect fired type usually designed to api 12k these devices are traditionally used to heat natural gas and oil.
The process to be heated typically oil or natural gas flows through the process coil.
Gas fired indirect water bath heaters designed in full compliance to api 12k specifications.
We are offering a wide range of indirect water bath heater.
The principals of operation of a salt bath heater are similar to that of a water bath heater.
A fire tube burner is submerged at the bottom of the heater vessel with a process coil submerged at the top.
Molten salts can be used at much higher operating temperatures.
A water bath heater works by submersing a process coil into a heated bath solution which then indirectly heats the process liquids and gasses to create energy.
Typically indirect bath heaters should achieve around 50 55 heating efficiency.
Usually the bath fluid is water but depending on the climate and heating requirements it can also be oil capable of heating process fluids to higher temperatures or a mixture of water and glycol used in colder climates to lower the freezing point.
The heater shell contains the firetube heating media water glycol or salts and process coil.
