Heat Recovery, Thermal Afterburning

Energy efficiency – Operating costs – CO2 balance

Low-CO2 heat sources

The many years of experience of the SCHWING Group with thermal processes, the technology and vertical integration available in-house, as well as the specific competence in the area of industrial furnaces and heat treatment plants, enable the production of particularly energy-efficient and environmentally friendly systems and solutions. In doing so, SCHWING relies on the use of low-CO2 heat sources wherever possible.

Thermal insulation of furnace housing and plant periphery

By using the highest quality insulation systems possible, SCHWING achieves excellent thermal insulating of all industrial furnaces and heat treatment equipment. Especially in combination with a heat recovery system, this feature ensures a significant optimization of energy costs and thus contributes to higher energy efficiency with a lower amortization period of your investment.

Heat recovery through heat exchangers / recuperators

To increase energy efficiency and reduce energy costs, it is advised to use the exhaust air from energy-intensive heat treatment and/or exhaust air cleaning afterburner processes. In this process, the hot exhaust air is passed through heat exchangers in which an indirect transfer of the thermal energy from the exhaust air to the heating or process air occurs (recuperator).

SCHWING offers cost-optimized heat exchangers with high efficiency for preheating the process air. Effective heat recovery ensures an optimum energy and CO2 balance for the entire heat treatment process.

Exhaust air cleaning through thermal afterburning

Industrial manufacturing processes are often accompanied by undesirable emissions such as odors, environmentally hazardous gases, dusts, etc., which must be eliminated by downstream exhaust air cleaning. Particularly in the heat treatment of plastics and composites, thermal afterburning of the exhaust air may be necessary due to the release of flammable or toxic gases and dust (cf. DIN EN 1539).

All SCHWING thermal afterburning systems comply with German and European legal requirements regarding emission limits for total carbon content, CO, NOx and dust (according to Technical Instructions on Air Quality Control, TA Luft) and contribute to the optimization of the CO2 balance of operational manufacturing processes.

To optimize energy efficiency, the exhaust air from thermal afterburning, which has a temperature of between 800 and 1100°C, can also be used specifically to heat the furnace system(s) or other customer-side heat processes (heat recovery).
