Indirect fired water bath heaters for the utility, processing, and upstream oil & gas industry.

Water bath heaters are commonly used in applications where bath process temperature does not exceed 170°F.

Overview

Hundreds of successful installations


Applications

Heating natural gas prior to pressure reduction to eliminate hydrate formation downstream of expansion valving.

Heating well stream fluids prior to phase separation.

Heating process streams to maintain fluid viscosity at a minimum to reduce HP pumping requirements.

Heating critical feed stocks that require tightly controlled film to bulk temperature differentials.

Heating turbine fuel gases to maintain a given dew point temperature.

Heating natural gas for upstream pressure regulation stations to prevent condensation due to Joule – Thompson effect.


Types of Heaters

Natural Draft: Burner relies on a stack to create negative pressure at the burner inlet.

Forced Draft: Heaters utilize small bore fire tubes plus a combustion air fan. High velocities reduce the “dead gas film” region, allowing reduced tube area compared to large bore tubes.

Vertical: Less industrial appearance, smaller footprint and totally enclosed to reduce burner noise and protect controls from environment.

Horizontal: Most commonly seen today.

Heater Components

Heater Shell: Atmospheric vessel designed in accordance with API-12K requirements containing the process coil, fire tube (combustion chamber) and heat media.

Process Coil: Pressure-containing part commonly designed in accordance with API-12K or ASME Section VIII Division 1 code.

Flue Gas Stack: Provides positive flue gas flow (draft) constructed of stainless steel with a clean-out tee at the bottom and a secure bird cage cover bolted to the top.

Fire Tube: Commonly U-tube configuration. Removable tube designed to efficiently transfer heat into surrounding heat media and minimize flue gas friction losses.

Flame Arrestor: Prevents transmission of flame within combustion chamber when exposed to external fuel source. Reduces temperature of fuel to withstand the internal forces of explosion.


Heater Components (cont.)

Expansion Tank: Reduces corrosion in the heater shell by keeping it liquid-packed and moving the wet-dry interface of the expanding bath media into the expansion tank.

Gas Train: Built to API-12K, with larger heaters using NFPA 87 as guideline.

Burner: The Eclipse Burner is a TERI standard, and uses an eductor to draw in combustion air and push combustion gasses through fire tube.

Pilot in a Drawer: Eliminates nuisance pilot outages with a dedicated combustion air pilot assembly. Allows all air required for proper combustion of the pilot gases to be pulled directly from outside of the main flame arrestor. Allows easy access to the pilot components for maintenance and inspection, and eliminates pilot outages due to a rich combustion chamber environment.
