Water Bath Heater
The configuration of the heater may differ depending on the process application. Usually, the heater consists of main body with coil tubes, burner, firetube and flue stack. Sometimes skid may consider an expansion tank.
The main body refers to the basic vessel into which the firetubes and process coils are inserted from opposite ends. The burner ignites the fuel gas or fuel oil and blow it into firetube to heat the water in the vessel, and the hot water heats the medium in the coils such as crude oil or raw natural gas. The process coils are “bathing” in the water, and that’s why it’s called a water bath heater.
The heater shell has two saddle types supports, which is cuboid form and mounted on skid or special-designed bases. Outlet temperature may vary, but usually don’t exceed 86-88 °C.
