Direct Contact LLC Heat Recovery Systems are designed to effectively improve energy efficiency by returning previously wasted heat to useful service within the facility.

ENERGY costs are rising! International competition for fuel, unrest in oil-producing countries, increased environmental regulations, and highly competitive markets all contribute to an ever-increasing focus on maximizing energy efficiency.

Many industrial processes expel heat or steam – with limited heat recovery systems in place. These systems consume fuel to raise process temperatures and most of them lose a significant heat to combustion exhausts, process vents, process products, and miscellaneous leakage. Steam systems, boilers, cooking and brewing processes and drying operations have potential for recovering a portion of their wasted heat.

These concepts are not new, but incentives are continually rising to investigate additional savings.

The rallying cry of ‘Reduce, Reuse and Recycle’ is no longer only found on  bumpers and the pop can machines, but echoes in the boardrooms and management meetings of businesses of all kinds and of any size.

It seems long ago that managers considered energy “too cheap” to bother recovering. Some heat losses, especially those associated with foul–prone streams, were too expensive to address.

The systems designed, built and proven by Direct Contact LLC (DCLLC) and our clients, are effectively recovering heat (and saving energy) in a variety of applications. Our systems have continued to evolve and improve over the years, as we’ve expanded applications, but they are all well-built and continue to perform as designed. Our experience ranges from relatively clean applications to foul-prone streams and they all pay for themselves.

Fuel savings is only one of the efficiencies provided by DCLLC designs. Because we drive temperatures of hot gas streams below their dew-points, water vapor that was otherwise vented is also recovered. Water from combustion is recovered and returned to processes, making the DCLLC system a ‘net producer’ of water. (Fuel streams are not generally considered a source of water!)

Another benefit of the DCLLC design is reduction of CO2 emissions. This is simply a result of higher energy efficiency offsetting the need to burn as much fuel as before adding our equipment.

Finally, because we use direct contact for heat recovery, our systems significantly reduce particulates and offer the ability to reduce a number of emissions with simple additions to the heat recovery stream. This allows our clients to reduce or eliminate their pollution-control equipment further downstream and, in some cases, significantly reduce odors, which improves their community Public Relations.
