Find the Right Heat Recovery Equipment

Not every waste heat source needs the same equipment. Some projects need steam generation. Some need process preheating. Others need boiler feedwater heating.
Gelan helps you choose the right waste heat recovery equipment based on your heat source, temperature, recovery target, and plant layout.

How Gelan Builds Reliable Waste Heat Recovery Equipment

Waste heat recovery equipment must do more than recover heat. It must fit your process duty, gas condition, pressure drop limit, site layout, and EPC review requirements. Gelan controls these details before fabrication, so the equipment is easier to approve, install, and operate.

01

Fit Your Actual Process Duty

Fit process calculation, energy balance, and project specs.

gelan icon

GELAN APPROACH

Your waste heat boiler, preheater, or economizer must match the real duty, not only the equipment name.
Gelan checks temperature, flow rate, heat load, pressure drop limit, steam demand, and utility target before fabrication.

Handle Dirty, Hot, and Corrosive Gas

Reduce fouling, blockage, corrosion, and maintenance risk.

GELAN APPROACH

Industrial waste heat recovery often handles high-temperature flue gas, dusty exhaust, acidic components, or process gas with fouling risk.
Gelan considers gas velocity, tube arrangement, cleaning access, corrosion allowance, and material selection during design review.

03

Recover Heat Without Excess Pressure Drop

Recover usable heat without disturbing upstream operation.

GELAN APPROACH

More heat recovery is not always better if it increases gas-side resistance.
Gelan reviews heat duty, gas velocity, flow distribution, and pressure drop limit to protect system stability.

Pass EPC Review with Traceable Records

Support EPC review before shipment and final handover.

GELAN APPROACH

For EPC and owner review, fabrication records are part of delivery.
Gelan can provide drawings, MTC, NDT records, hydrotest reports, dimensional checks, and handover documents based on project requirements.

05

Fit Site Layout and Installation Limits

Make installation easier for new-build and revamp projects.

GELAN APPROACH

Many waste heat recovery projects are tied to existing furnaces, boilers, reformers, incinerators, DTO units, or turbine exhaust systems.
Gelan can support layout coordination, duct interface review, sectioned fabrication, and modular delivery when space, transport, or installation conditions are limited.

Where Our Waste Heat Recovery Equipment Is Used

Waste heat recovery equipment is used in industrial projects where flue gas, exhaust gas, or process waste heat still carries reusable energy. Gelan supports custom heat recovery equipment for refinery, petrochemical, hydrogen production, and power-related systems.

Used in fired heaters, boilers, coking units, and other refinery systems to recover flue gas heat for steam generation, feedwater heating, or process preheating

Refining

Supports petrochemical plants in recovering waste heat from cracking furnaces, process heaters, thermal oxidizers, and exhaust systems to improve heat utilization and reduce fuel loss

Petrochemical

Applied around reformers, steam systems, and related heating sections to recover high-temperature waste heat for steam generation, feed preheating, and efficiency improvement in hydrogen production projects

Hydrogen Production

Used in boiler, HRSG, turbine exhaust, and other energy systems to recover exhaust heat, improve thermal efficiency, and reduce overall energy loss in power-related projects

FAQs About Pressure Vessels and Process Tanks

Q1: How do I know if my waste heat is worth recovering?

Your waste heat may be worth recovering if it still has usable temperature, stable flow, and a nearby reuse point.
You can review these points first:

  • High stack or exhaust temperature
  • Stable gas or process flow
  • Nearby steam, hot water, air preheating, or feedwater heating demand
  • High fuel cost or energy-saving target
  • Acceptable pressure drop and site space

If you already have heat source data, Gelan can help check whether a waste heat recovery system is practical for your project.

Recovered waste heat can be used for steam generation, feedwater heating, air preheating, fuel preheating, feedstock preheating, or process heat recovery. In most industrial projects:
  • Waste Heat Boiler / HRSG helps generate steam or hot water
  • Preheater helps preheat air, fuel, feed, or process media
  • Economizer helps preheat boiler feedwater
The right use depends on your heat source and plant utility demand.
Gelan provides custom waste heat recovery equipment for industrial projects, mainly including:
  • Waste Heat Boiler / HRSG
  • Preheater
  • Economizer
These units are used for exhaust heat recovery, flue gas heat recovery, steam generation, feedwater heating, and process preheating.

A WHRU means Waste Heat Recovery Unit. It is a general term for equipment that recovers usable heat from exhaust gas, flue gas, turbine exhaust, or process waste heat.
In real projects, a WHRU may refer to a waste heat boiler, HRSG, preheater, economizer, or a custom heat recovery package.

Yes. Waste heat recovery equipment can often be added to existing furnaces, boilers, reformers, incinerators, DTO units, turbine exhaust systems, or exhaust ducts.
For revamp projects, the key checks are:

  • Available site space
  • Duct connection
  • Shutdown window
  • Transport limits
  • Pressure drop impact
  • Maintenance access

Gelan can support sectioned fabrication or modular delivery when the site layout is limited.

It can, if pressure drop, gas resistance, or duct layout is not reviewed carefully.
A good exhaust heat recovery system should recover usable heat without disturbing upstream operation. Gelan reviews pressure drop limits, gas velocity, duct connection, and equipment layout before fabrication.
This helps reduce risks such as higher resistance, unstable draft, or site modification after delivery.

For a faster quote, send these project details:

  • Heat source type
  • Inlet and outlet temperature
  • Gas or medium flow rate
  • Pressure and pressure drop limit
  • Gas or medium composition
  • Dust, ash, sulfur, chlorine, or corrosive components
  • Recovery target: steam, feedwater heating, air preheating, or process heating
  • Site layout or delivery limits

These details help Gelan review the basic waste heat recovery system design direction and prepare a more accurate quotation.

Yes. Gelan supports EPC teams, engineering companies, and plant owners with custom equipment manufacturing and project coordination.
For industrial waste heat recovery projects, Gelan can support:

  • Technical clarification
  • Custom fabrication
  • Inspection records
  • NDT and hydrotest reports
  • Packing and shipment planning
  • Handover documents

This helps the project move more smoothly through review, fabrication, delivery, and installation.

Gelan mainly provides custom waste heat recovery equipment. Based on project scope, we can also support related engineering coordination, equipment interfaces, modular fabrication, inspection documents, and delivery planning.
If your project needs a broader waste heat recovery solution, Gelan can work with your EPC or engineering team around the required equipment scope.
