Waste Heat Recovery Units

Increase Plant Efficiency with a Waste Heat Economizer

Enerquip’s robust high-temperature waste heat economizers are built based on rigorous API standards practiced throughout the world. Our innovative industrial waste heat recovery technology is utilized in our thermal fluid heaters and all the heaters we build, making our heating equipment some of the most efficient on the market.

Our waste heat economizers enable significant waste heat recovery and are key components of the complete industrial heating systems we provide to customers in a variety of industries, including chemical, refinery, tank terminal, and asphalt.

To help your facility run more efficiently, we offer several designs and sizes, including finned pipe and bare pipe. These waste heat recovery units capture the energy from hot gas exiting incinerators, oxidizers, turbines, gasifiers, and other industrial equipment. That energy is then used to heat a variety of heat media, including hot oil (heat transfer fluid), asphalt, glycol, and other solvents, which then transfer the heat to other users.

Waste Heat Economizer Applications

Waste heat economizers have a variety of industrial applications. They can be sold as standalone equipment or partnered with our serpentine coil thermal fluid heaters for the greatest efficiency. Here are some common applications of waste heat economizers:

• Heating thermal fluid in an economizer using turbine exhaust gas
• Heating thermal fluid in an economizer using the flue gases from a thermal oxidizer, incinerator, or gasifier
• Heating asphalt in an economizer using the exhaust gas from a thermal oxidizer or incinerator
• Heating water/glycol in an economizer using the exhaust gas from a thermal oxidizer or incinerator

Waste Heat Economizer Design Features

Economizers from Enerquip can also handle heavy ash or dirty gas that is very common with applications in a variety of industries. The following waste heat economizer design features ensure that our units will withstand high particle gas:

• Soot blower lanes and soot blowers
• Castable refractory throughout the unit
• Maintenance access between sections
• Removable header boxes

Benefits of Waste Heat Recovery Units

Waste heat recovery units can deliver various benefits, including:

• Saves Energy and Costs: Industrial waste heat recovery units capture waste heat for reuse throughout the facility. Implementing a heat waste recovery system can result in lower energy consumption and a significant reduction of energy costs overall.
• Improved Efficiency: Waste heat recovery units can capture and reuse heat that would otherwise be wasted, improving the efficiency and fuel economy of the facility.
• Decreased Capital Costs: A waste heat recovery unit offers a less expensive solution than other energy-saving systems, allowing a facility to reuse its heat waste with a lower investment.
• Increased Sustainability: Reducing greenhouse gas emissions and energy consumption using waste heat recovery units can help a facility increase sustainability. Our waste heat recovery units recover heat from incineration and other processes. Often, the facility can benefit from selling carbon credits back to the industry or be eligible for local and federal grants, tax credits, and programs by installing a waste heat recovery unit.

Reclaiming Lost Energy

Waste heat recovery captures and repurposes heat that would otherwise be lost, turning it into valuable energy for industrial processes. From exhaust gases to flue emissions, there are multiple ways to harness this heat, reducing both energy costs and greenhouse gas emissions. Here’s a look at key methods for improving energy efficiency through waste heat recovery.

Exhaust Waste Heat Recovery

Heat energy can be lost as it is exhausted from the facility. Exhaust waste heat recovery is a basic method of recovering waste heat energy. It allows exhaust gases to be captured from the flue or stack and reused in preheating incoming gas to improve the combustion processes in ovens, furnaces, and boilers.

Heat Pump Waste Heat Recovery

Heat pumps transfer waste heat from industrial processes to other areas throughout the facility where it can be repurposed. Heat pumps use a minute amount of energy to transfer heat between locations rather than directly generating it. The heat energy is captured for waste heat recovery applications by a fluid like water vapor and transferred where it is needed using a piping system.

Flue Gas Heat Recovery

A waste heat recovery unit can recover flue gas heat from kilns, furnaces, boilers, and other equipment. Waste heat recovery from flue gases can be an effective method of improving energy efficiency and reducing greenhouse gas emissions. A common method of recovering waste heat from flue gases is by using heat exchangers. A heat exchanger transfers heat from the flue gas to a fluid, allowing the heat energy to be used throughout the facility.

Preheating Asphalt With Waste Heat Recovery 

Asphalt needs to be heated to keep it pliable for pumping. Our waste heat recovery units help to preheat the asphalt from 180F to 300F for this purpose, before it’s fed to a final heater for production.
