Clean Power From Waste and Biomass
We design and deliver proven, high‑efficiency technologies that convert waste and sustainable biomass into reliable, low‑carbon electricity, heat and cooling facilities.
Our portfolio spans all sizes of waste and wood fired power plants. Using advanced, steam and thermal oil heat exchanges, turbines, emissions‑control systems and digital plant controls. Every system is engineered for performance, compliance, and long‑term value.
Waste‑to‑Energy: Small Units
Ideal for: industrial estates, waste operators, manufacturers, data centres, and behind‑the‑meter users seeking secure, low‑carbon energy with predictable operating costs.
Core technologies
- Thermal conversion: step‑grate combustion or modular gasification tailored to waste stream (RDF/SRF, biomass‑derived fractions).
- Energy recovery: water‑tube or fire‑tube boilers generating saturated/superheated steam for a compact steam turbine or ORC (Organic Rankine Cycle) set.
- Emissions control: multi‑stage flue gas treatment (cyclone/multicyclone, baghouse filters, SCR/SNCR for NOx, acid‑gas scrubbing, activated carbon for dioxins/mercury).
- Electrical integration: synchronous generator with islanding capability; options for direct‑wire to on‑site loads, export to grid, or CHP heat offtake.
Key benefits
- Small footprint & modular build: rapid deployment, scalable in parallel lines.
- Waste minimisation: diverts material from landfill, recovers energy and reduces disposal costs.
- Stable on‑site power: hedges grid volatility; option for heat recovery to boost overall efficiency.
- Compliance built‑in: engineered to meet stringent emissions requirements and reporting.
Biomass Power Stations
Fuel‑flexible, base‑load renewable generation delivering dependable output with the option for CCHP to serve industrial heat and cooling networks.
Core plant architecture
- Fuel handling & preparation – reception, screening, drying (as needed), metering to the boiler.
- High‑efficiency boiler – moving or reciprocating grate for chips/pellets/agri‑residues; fluidised bed options for broader fuels.
- Steam and thermal oil cycle – superheated steam to back‑pressure or condensing steam turbines; air‑cooled or water‑cooled condensers depending on site constraints.
- Emissions control – baghouse filters, SCR/SNCR, dry/wet scrubbing, and activated carbon dosing for ultra‑low emissions.
- Electrical & controls – generator, protection, switchgear, and advanced DCS/PLC for automated, safe plant operation.
Why biomass?
- Dispatchable renewable: supports grid stability vs. intermittent sources.
- CCHP capable: high total efficiency where heat is recovered.
- Sustainable fuels: options include forestry residues, energy crops, certified wood fuels, and Biomass rich fibers resourced from all types of waste streams.
Boilers, Turbines & Filters: How We Engineer Clean Power
Boilers
- Water‑tube designs for higher pressures and temperatures, maximising steam quality and output.
- Grate combustion (waste/biomass) for robust fuel tolerance; fluidised bed for challenging fuels and low NOx.
- Integrated economisers and air preheaters to lift efficiency and reduce fuel burn.
Steam Turbines
- Back‑pressure for CHP (process heat + electricity).
- Condensing for maximum electrical yield.
- ORC alternatives for small‑scale or lower‑temperature heat sources.
Filters & Emissions Control
- Baghouse filters for <5 mg/Nm³ removing sub micro particulates (design‑dependent).
- SNCR/SCR for NOx abatement; dry/wet scrubbers for acid gases (HCl, SO₂).
- Activated carbon dosing to capture dioxins/furans and mercury.
- Continuous emissions monitoring (CEMS) for real‑time compliance
Process Overview (Typical Line‑Up)
Fuel In → Preparation → Boiler/Furnace → Steam Generation → Turbine/Generator → Condenser → Flue Gas Treatment → Stack → Ash Handling → Grid/Direct‑Wire/Heat
Each stage is engineered for availability, maintainability, and safe operations, with redundancy for critical services (ID/FD fans, feedwater pumps, dosing skids) where required.
Performance & Compliance
- Electrical efficiency: typically 18–35% (fuel & scale dependent); higher total efficiency with CCHP.
- Availability targets: >90% with planned outages, supported by predictive maintenance and spares strategies.
- Emissions: designed to comply with Industrial Emissions Directive (IED) / Best Available Techniques (BAT) conclusions and local permitting requirements.
- Residues: bottom ash and fly ash managed via certified routes; potential adding value, assessed case‑by‑case.
Direct‑Wire & Grid Integration
- Direct‑wire to reduce transmission losses and grid charges; supports resilience for critical processes.
- Grid connection studies (load flow, fault levels, protection coordination) and G99/G100 compliance (or local equivalent).
- Islanding and black‑start options for site security; export metering and PPA structuring available.
Digital, Safety & O&M
- Advanced controls (DCS/PLC) with automated start/stop, ramping, and emissions optimisation.
- Condition monitoring for turbines, rotating plant, and baghouse differential pressures.
- Functional safety: SIL‑rated safety instrumented functions for fuel, steam, and combustion systems.
- O&M models: owner‑operator, LTSA with OEMs, or fully outsourced O&M—each with KPIs for heat rate, availability, and emissions
