Exhaust Gas Silencers for CHP (Combined Heat and Power) Plants

NovaNox® exhaust gas silencers for CHP plants are also used in combined heat and power plants to reduce noise emissions. Combined heat and power plants generate heat and electricity by burning fuel. They are typically fuelled by diesel or gas engines, resulting in higher efficiency than comparable systems. Applications for CHP plants include, for example, agriculture, the food industry, or industrial facilities.

NovaNox® exhaust gas silencers for CHP plants are custom-made and precisely tailored to your specific requirements profile. They absorb sound waves of medium and high frequencies, thereby effectively attenuating noise emissions. Additionally, by incorporating resonance chambers, the low-frequency hum typical of CHP plants is filtered out.

For noise attenuation in CHP plants, absorption silencers, reflection silencers, and combination silencers can be utilised. NovaNox® absorption silencers are particularly effective in reducing sound levels at medium and high frequencies. Furthermore, these silencers cause minimal pressure loss within the system. Reflection silencers, on the other hand, are especially effective at low frequencies. They also excel due to their durability and consistent performance.

The various silencers are installed individually or as combination silencers, depending on the system. The NovaNox® team is on hand to assist with individual planning and help you develop the perfect exhaust gas silencer for your CHP plant to meet your specific requirements.

NovaNox® absorption silencers for CHP plants are custom-manufactured to suit your specific installation situation. The interior of the silencer consists of porous material, typically rock wool or glass wool as insulating material. This absorbs the generated sound and converts it into heat. A stainless steel perforated tube, encased with stainless steel mesh, runs through the insulating material, allowing sound to dissipate.

NovaNox® absorption silencers are installed for medium and high frequencies. In combined heat and power plants, they are predominantly installed in combination with reflection silencers to optimally reduce noise emissions.

NovaNox® reflection silencers for CHP plants, also known as chamber silencers, utilise an entirely different method of sound attenuation compared to absorption silencers. They are named after the reflection chambers located at the rear end of the silencer. However, their general structure resembles that of absorption silencers. A stainless steel perforated tube, wrapped with stainless steel mesh and embedded in insulating material, is also connected to the silencer body.

As the term "chamber silencers" suggests, reflection silencers contain multiple chambers. These chambers operate on the principle of sound reflection and sound wave superposition. The sound repeatedly passes through the interior spaces of the chambers, leading to sound pressure amplitude reduction and a decrease in sound pressure peaks. Baffle plates, cross-section enlargements, and cross-section constrictions enable optimal reflection and the associated reduction of noise emissions.

NovaNox® reflection silencers for CHP plants are used to reduce noise emissions at low frequencies. They are preferably installed in combination with absorption silencers in combined heat and power plants to ensure optimal results.

NovaNox® combination silencers for CHP plants are used to cover a particularly broad spectrum of frequencies. They are a combination of absorption silencers and reflection silencers. They can be installed separately as both a middle and end silencer within the system, or integrated into a single silencer unit.

NovaNox® surface treatments enhance both the service life and safety, as well as the aesthetics, of exhaust gas silencers for CHP plants. Through surface treatment, we can offer you a permanently corrosion-free, secure, and robust surface for your exhaust gas silencers. With our in-house powder coating and painting facility, surfaces can be finished quickly and to a high standard in all RAL colours. Furthermore, we offer heat-resistant painting, galvanising, and powder coating, as well as pickling and passivating, to ensure optimal corrosion protection.

Thanks to our many years of experience in the realisation of customised silencers, we develop and produce individual exhaust gas silencers for CHP plants for manufacturers of machinery, plant and vehicle technology, industrial facilities, agricultural enterprises, or other industrial applications.

To effectively and optimally utilise the available installation space, we undertake the complete planning of dimensions, arrangement, and materials. This precise coordination positively influences the performance results of NovaNox® exhaust gas silencers for CHP plants and optimally reduces noise. Furthermore, selecting the optimal materials maximises the performance capability of your NovaNox® exhaust gas silencer for CHP plants.

NovaNox® exhaust gas silencers for CHP plants are made from tested and high-quality steel or stainless steel. The internal insulation material consists exclusively of first-class fibreglass wool, stainless steel wool, or rock wool.

Furthermore, in cases of high condensate accumulation, non-hygroscopic insulating materials can be used. This prevents moisture retention, thereby avoiding permanent condensate build-up within the exhaust gas silencer. Preventing condensate formation, in turn, maintains the silencer's performance level and significantly extends its service life.

Manual Welding

With the aid of our trained personnel and extensive welding expertise, we not only utilise automated welding processes but also produce hand-welded exhaust gas silencers. Through manual welding, we can offer you a cost-effective alternative with rapid turnaround times. It is primarily used for single-piece productions as well as small and medium-sized series. Hand-welded exhaust gas silencers are manufactured on modern welding tables. Our in-house jig construction ensures dimensional accuracy. Furthermore, repeatability can be guaranteed at all times, even with high tolerances.

Automated Welding

For our automated welding process, we utilise state-of-the-art welding robots. Automating these manufacturing processes increases the speed and efficiency of the operation. This ensures consistently high quality when manufacturing large volumes. Additionally, the automated welding process offers extremely high precision. This allows even very complex exhaust gas silencers for CHP plants with demanding tolerance requirements to be realised.
