Pick
direct steam injection is an excellent alternative to conventional sludge
heating methods, offering dramatic reduction in captial and installation
costs while providing exact temperature control. The benefits of preheating
sludge upstream of the thermophilic digesters are well documented. However,
doing so is a costly proposition, especially with traditional processes
using indirect heater exchangers.
Pick
Heaters, Inc. offers steam injection heaters designed specifically for
sludge service. These couple Pick's proven method of steam injection
with a fabricated housing - available as inline or elbow configuration
to best suit your sludge piping arrangement. Generous internal clearances
and smooth contours impose negligible pressure drop and allow free passage
of stringy matter. Hard facing is available on the internal surgaces
of the housing and the injector can be surface hardened to resist erosion
when heating sludge containing abrasive grit.
Applications
include:
Thermophilic
Digestion Process
A direct steam injection (DSI) heater offers several advantages over
an indirect heat exchanger in this process. It is compact, imposes negligible
pressure drop, and is easy to maintain.
Anaerobic
Treatment of Organic Waste
The Pick Heater can handle large volumes of liquid with a low liquid
side pressure drop, while maintaining the tight temperature control
necessary in the anaerobic process.

Steam Injection Heaters for Swine Manure
When a major meat processing company committed to building a waste to
energy facility, they called on Pick.
