Product Overview

Our multi fuel gas and chemical waste heat boiler is engineered to capture and reuse excess thermal energy from petrochemical, refinery, and chemical processing streams. By converting low‑grade waste heat and flue gases into high‑quality steam, the unit lowers fuel consumption, reduces carbon emissions, and improves overall plant efficiency. Designed for continuous duty cycles, the boiler can be tailored to handle a wide range of fuel gases—including natural gas, LPG, biogas, and process off‑gases—while tolerating the corrosive components typical of chemical waste streams.

The modular construction allows for onsite assembly and future capacity upgrades without major downtime. Integrated control logic synchronises with existing DCS/SCADA systems, providing real‑time monitoring of temperature, pressure, and emissions to meet stringent regulatory requirements.

All parameters are customizable per order. Our engineering team works closely with the client to fine‑tune the design for the exact waste‑heat profile and steam demand of the facility.

Application Scenarios

• Refinery desulfurization units – recover heat from hydrogen sulfide‑rich off‑gas.
• Petrochemical cracking furnaces – capture flue gas temperature differentials for steam generation.
• Chemical synthesis reactors – utilize exothermic reaction gases that contain corrosive compounds.
• Waste‑to‑energy plants – burn low‑grade landfill gas while extracting maximum heat.
• Industrial drying processes – provide supplemental steam while reclaiming dryer exhaust heat.

Because the system is designed for multi‑fuel operation, a single boiler can serve several process lines, simplifying plant layout and reducing capital expenditure on separate heat‑recovery equipment.

Competitive Advantages

1. Proven fuel flexibility – The boiler tolerates high‑moisture, high‑acid gases without performance loss, eliminating the need for separate gas‑cleaning trains.
2. High thermal efficiency – Optimised heat‑exchange geometry and advanced condensation technology achieve up to 95 % efficiency, translating into measurable fuel cost savings.
3. Scalable modular design – Standardised pressure vessel sections can be added or removed in the field, allowing capacity adjustments of ±30 % without major shutdowns.
4. Integrated emissions control – Built‑in low‑NOx burners and automatic soot‑blowdown keep stack emissions within EU/US limits.
5. Seamless digital integration – Open‑protocol communication ensures the boiler fits into existing plant automation, providing instant diagnostics and predictive maintenance alerts.

Frequently Asked Questions

What is the minimum order quantity (MOQ) for a custom‑designed boiler?

We accept single‑unit projects for pilot or specialty installations. For larger plants, volume discounts apply from the second unit onward.

Can the boiler be adapted to specific chemical waste compositions?

Yes. Our materials‑selection team can specify corrosion‑resistant alloys, ceramic linings, or internal coatings to match the aggressiveness of your waste gases. Design changes are incorporated during the engineering phase at no extra tooling cost.

What is the typical lead time from order to delivery?

Standard models are shipped within 15‑30 days after receipt of the purchase order and engineering sign‑off. Fully customized units require 30‑45 days, depending on material specifications and certification requirements.

What warranty and after‑sales support are provided?

Every boiler comes with a 24‑month warranty covering material defects and manufacturing faults. Our global service network offers on‑site commissioning, training, and 24/7 technical hotline for rapid troubleshooting.
