Indirect Heating Systems

Heat process streams without direct flame contact

Schlumberger provides four types of indirect heaters employing NATCO separation technology. In each system, heat is liberated in a separate chamber and then transferred to the process stream through a medium such as water, water and glycol, steam, salt, or flue gas to deliver furnace output ratings from 50,000 to 50,000,000 Btu/h.

The primary advantages of indirect heating are that the heat medium transfers heat evenly, and the coil’s inside wall temperature is lower than that of direct heaters, which reduces scaling, coking, and plugging.

Indirect heaters are widely applicable to the petroleum industry and in power generation and industrial systems. NATCO separation technology means that they operate reliably and efficiently in both standard and custom applications.
