Combined Heat and Power (CHP)

CHIMNEY & FLUE SYSTEMS:

Simple Solution with Double Benefits

Decentralized Combined Heat and Power (CHP) and trigeneration (CCHP) systems are increasingly adopted across the UK commercial and industrial sectors as part of a broader strategy to reduce energy costs and carbon emissions. By simultaneously generating electricity and utilizing the waste heat for space heating, domestic hot water, or industrial processes, CHP systems can achieve overall efficiencies exceeding 90%.

Important to know…

CHP systems can be fuelled by natural gas, biogas, diesel, or biomass, each presenting specific challenges in terms of exhaust gas temperature, pressure, and condensate composition. As such, the flue system must be carefully selected to ensure long-term performance, safety, and compliance. Taking in account that the CHP´s reduce energy costs and carbon emissions, by simultaneously generating electricity and utilizing the waste heat for space heating, this dual-generation approach not only supports the UK’s energy transition goals but also offers significant operational savings for facilities such as hospitals, data centers,

manufacturing plants, and large commercial

buildings.

The Role of the Chimney…

Jeremias UK offers a complete range of flue systems specifically engineered for CHP applications, including:

• DW-FS: A pressure-tight, corrosion-resistant system suitable for both positive and negative pressure operation, offering flexibility across a wide range of applications

• DW-KL: A double-wall, mineral-insulated stainless-steel system for more demanding installations, offering enhanced thermal and acoustic insulation.

• EW-KL: A single-wall stainless steel system with conical flange seal, suitable for exhaust gas temperatures up to 600°C.

Solutions

Explore our range of stainless steel chimneys and flues.

Freestanding industrial stacks

At Jeremias UK, we design and manufacture freestanding industrial stacks, also known as windshields, at our Blackpool facility, the largest production site in the UK for this type of solution. These self-supporting structures are engineered to accommodate single or multiple flue liners, and are the go-to solution for data centres, energy centres, and mission-critical infrastructure where flue heights exceed 25 metres and structural independence is essential.

High pressure twin-wall flue systems

DW - KL50: Twin wall insulated, factory-made exhaust system with special conical metal to metal jointing for high temperatures and high pressures.

DW - FS50: The DW FS system of Jeremias is a twin wall insulated, factory made exhaust system with flanged connection and with graphite gasket between flanges, that guarantees the tightness for high pressure and high temperatures.

Industrial Silencer Technologies

Jeremias offers a modular and scalable silencer portfolio to meet the acoustic and operational demands of each project: Absorptive Silencers (ASD / AED), Resonance Silencers, Combined Silencers (KSD / KED / KEL), Splitter Silencers (KUD), Inline and Chimney-Top Silencers and Plastic Silencers (ASD-PP)

Structural Support systems

Jeremias UK designs and manufactures a wide range of self-supporting and guyed flue mast systems, providing structural support for modular chimney systems where building attachment is not feasible or where additional height is required to meet dispersion or safety regulations.

Twin Wall Insulated Chimney

DW-ECO 2.0 304: Multi-purpose factory-made twin wall insulated chimney system made in stainless steel AISI 304 in the inner liner and AISI 304 outer liner.

DW-ECO 2.0 316: Multi-purpose factory-made twin wall insulated chimney system made in stainless steel AISI 316 in the inner liner and AISI 304 outer liner.
