Waste Heat Recovery for Improved Efficiency and Environmental Sustainability

Waste heat recovery solutions help recover heat that is wasted and can otherwise be put into practical use. Different technologies can be used such as passive air preheaters, rotary generators, and recuperative and regenerative burners. Waste heat is a valuable source of energy that can be used in the ceramic, food, steel and iron, and other industries and facilities such as office buildings, airports, and industrial plants.

How energy is wasted as heat

Energy is wasted as heat when released during combustion processes or transferred from equipment and facilities through radiation, convection, and conduction. A significant amount of energy is released into the environment in the form of liquids, air streams, and exhaust gases. Waste heat that enters the environment mixes with groundwater or air and useful energy is lost.

Sources of waste heat include heat released from the surface of equipment, hot water released by industrial facilities, and combustion gases that are discharged into the air. Exhaust gases are generated by manufacturing equipment such as melting furnaces, steel heating furnaces, solid waste incinerators, open hearth furnaces, and baking and drying ovens.

Heat is lost across industry sectors such as food and beverage, iron and steel, forest products, chemicals, and petroleum refinishing. Other sectors that can benefit from waste heat recovery include plastics and rubber, textiles, transportation equipment, fabricated materials, and heavy machinery.

Advantages of Waste Heat Recovery

The utilization of waste heat helps increase production efficiency, reduce harmful carbon dioxide emissions, and lower fuel consumption. Businesses enjoy further benefits such as reduced carbon taxes and fuel consumption. Resource conservation is also a major benefit in a world that has limited resources. Using nonrenewable resources as efficiently as possible is the key to conservation. Waste heat recovery also contributes to waste reduction given that manufacturing and heating processes generate waste. The heat produced by chemical reactions and fuel combustion is one source of waste that can be reused instead of released into the environment.

What we offer

KitCOG is an advanced solution that can be installed in office buildings, industrial operations, hotels, and airports. Free thermal energy is supplied to buildings with gensets which are natural gas or diesel generators. Waste heat is used as thermal energy produced while the generators are running. This compact system is suitable for both outdoor and indoor settings and only requires the equipment to be fitted and interconnected into a solid skid in indoor operations or a container in outdoor settings. The system supplies thermal energy while the genset generates electricity. Fuel consumption does not increase, and energy can be supplied in the form of steam, hot water, or chilled water.

Waste heat recovery of KitCOG offers multiple advantages such as reduced costs, improved resource efficiency, and reduction in emissions, including sour gas and carbon monoxide gas. In normal generators, heat is lost as exhaust gases or hot water from catalytic exhausted pipe and engine jackets instead of being transformed into useful energy. This heating energy that otherwise is lost can be delivered to commercial and industrial buildings.
