Indirect fired water bath heaters are a type of oilfield heater designed to increase the temperature of process gases. They are installed at the well head, upstream of natural gas pressure reduction systems, at power generation locations, upstream of gas turbines to control dew point of fuel gas.
Indirect heaters are generally designed to API Spec 12K which “covers minimum requirements for the design, fabrication, and shop testing of oilfield indirect type fired heaters used in the production of oil, gas, and their associated fluids.” They are called indirect heaters because a medium (typically water glycol mixture) is used to transmit heat generated by the burner to the process gas. This results in uniform heating of the process gas.
Sungov manufactures these indirect fired line heaters (water bath heaters) for natural gas and other fuel gas applications backed by design from a premier European company. These are offered as a complete skid mounted packaged system typically consisting of a combustion chamber with burner element, a heater shell with fire tubes and process coils, an electric or pneumatic control system with safety interlocks. Vessels and heat exchangers Code stamped to ASME Sec VIII Div. 1, control systems certified to ATEX/Ex Proof available as options.
Frequently Asked Questions
Q 1. What are industrial indirect fired water bath heaters?
Industrial indirect fired water bath heaters are heating systems that transfer heat through a water medium without direct flame contact. They use an indirect heating chamber to warm liquids or gases, providing stable, efficient heat for industrial processes.
Q 2. How do indirect gas-fired process heaters work?
Indirect gas-fired process heaters burn fuel in a separate combustion chamber and transfer heat through a heat exchanger. This design prevents combustion gases from mixing with the process fluid, ensuring clean and consistent heating for sensitive applications.
Q 3. Where are indirect fired heaters for oil and gas used?
Indirect fired heaters for oil and gas are used in heating crude oil, natural gas, and other hydrocarbons during processing, storage, and pipeline operations. These heaters improve fluid flow, prevent hydrate formation, and support refinery and field operations.
Q 4. What advantages do indirect heating solutions offer for industrial use?
Indirect heating solutions for industrial use provide precise temperature control, reduced contamination risk, enhanced safety, and longer equipment life. By isolating combustion gases from process fluids, these systems support reliable and efficient thermal management.
Q 5. Who are the leading indirect fired air heaters manufacturers?
Leading indirect fired air heaters manufacturers design and supply systems for HVAC, drying, and process heating applications. They offer customized solutions, high-efficiency heat exchangers, and robust after-sales support to meet diverse industrial requirements.
