Water Bath Heater

General Introduction


Water Bath Heaters are designed to heat high pressure fluids and gas coming from the well or pipeline.Water bath heaters (water jacket furnace)used in oil and gas industry for heatingmedium of the pipeline to prepare for further technology needs. It also called indirect bath heater.




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.

Burner Management System

HC also offers water bath heaters with several types of Burner Management System (BMS). BMS is widely use in industrial heaters, boilers, and furnaces. BMS is designed to perform several functions, such as protection, operation, control, monitor, and communication. BMS controls and monitors pilot lines, fuel gas lines, temperature, pressure of whole unit, as well as shutdowns and alarms in case of emergency. BMS is very essential for oil & gas heaters. However, there are several types of BMS offered by HC.

  • HC supplies three types of BMS for industrial heaters:
  • Simple mechanical site operated control panel. It does not require complex cabling, and expensive components, and easy to operate.
  • Control system with microprocessors. Control system with microprocessor provides additional digital control features and enable send and receive signals from remote control panel.
  • Third type is BMS with PLC and additional digital control and operating functions. BMS enables to connect unit with SCADA or main control system of facility. BMS with PLC has a lot of advantages over conventional BMS, but requires more cables, more electric protection, and expensive components.

As BMS is installed near the burner of heater, it shall be explosion proof and SIL-rated. HC Petroleum Equipment provides water bath heaters and other industrial indirect fired heaters with comprehensive and reliable BMS, meeting project requirements and client’s expectations both in price and quality.
