Frequently Asked Questions
Which combustion technology is right for us?
Fuel chemistry and variability drive the choice: moving-grate for stable woody fuels; BFB/CFB for mixed or high-ash fuels needing better mixing and turndown.
Can you integrate with our district heating network?
Yes—HX station design, hydraulics, controls, metering, and storage are engineered to your supply/return regime and ΔT targets.
How do you ensure emissions compliance?
We combine primary measures (staged air, FGR) with the right secondary controls (baghouse/ESP, SNCR/SCR, sorbents) and integrate CEMS and testing provisions.
Do you also handle permitting and tendering?
Yes—permitting basis, Employer’s Requirements, bid evaluation, and owner’s-engineer support through detailed design and commissioning.
What’s the first step?
Share fuels, target capacity, DH temperatures/pressures, and whether CHP is in scope. We’ll propose scope, programme, and the required studies.
Ready to get started?
Tell us about your fuels, heat/CHP capacity, and district-heating parameters. We’ll prepare a tailored engineering package and schedule.
