Frequently Asked Questions
Waste Heat Boiler Technical FAQ
Comprehensive answers to the most frequently asked questions by plant managers, energy engineers, and EPC contractors considering waste heat recovery projects.
Which process gases can your waste heat boilers handle?
Waste heat boiler configurations can be reviewed for clean and dust-laden flue gases from a range of industrial processes. The temperatures below are indicative source examples:
High Temperature Sources:
- • Cement kiln exhaust (300-400°C)
- • Glass furnace flue gas (400-600°C)
- • Steel reheat furnace (350-700°C)
- • Lime kiln exhaust (300-500°C)
Medium Temperature Sources:
- • Gas turbine exhaust (350-550°C)
- • Diesel engine exhaust (300-450°C)
- • Incinerator flue gas (200-400°C)
- • Process heater exhaust (250-500°C)
Gas composition, dust loading, fouling tendency and corrosive constituents are reviewed during material, layout and cleaning-system selection. Suitability is confirmed from the project data.
How do you select a suitable boiler configuration for a project?
Boiler type and layout selection is based on the available process conditions, project requirements and site constraints:
- • Thermal review: Gas flow rate, temperature profile, heat-transfer calculations and required steam parameters
- • Mechanical design: Pressure drop limitations, structural support, thermal expansion, and maintenance access
- • Site integration: Available space, transportation limits, existing infrastructure, and installation requirements
- • Configuration options: Vertical/horizontal natural circulation, fire tube/water tube, modular sections, or hybrid designs
The proposal-stage review scope is confirmed according to the information available and the requirements of each project.
What design features improve efficiency and long-term reliability?
Design review balances heat recovery, gas-side pressure drop, thermal expansion, maintenance access and expected operating conditions:
Heat Transfer Enhancement:
- • Bare or finned tubes selected by service
- • Tube pitch and arrangement reviewed by project
- • Gas / water-steam flow arrangement selected by service
- • Multi-pass arrangement when suitable
Reliability Features:
- • Drainage provisions reviewed for the arrangement
- • Thermal-expansion provisions defined by design
- • Material selection based on service conditions
- • Inspection and maintenance access considered
Efficiency, footprint, pressure drop and design life are project-specific. They are confirmed only after review of the process data, selected configuration, materials and applicable design criteria.
What is the typical ROI and payback period for waste heat recovery projects?
ROI and payback are not fixed equipment values. They depend on recoverable heat, annual operating hours, steam demand, energy prices, plant integration, maintenance assumptions and local commercial conditions.
ORL can support a preliminary technical review when the required process and commercial inputs are available. Any economic estimate should be verified against the customer's actual operating data and evaluation method.
How long does delivery, installation, and commissioning take?
Delivery, installation and commissioning schedules depend on engineering scope, drawing approval, material availability, code review, inspection hold points, module size, shipping route and site conditions.
A project-specific schedule is provided after the supply boundary and technical documents are confirmed. Planned shutdown windows and site responsibilities should be reviewed with the customer before the schedule is finalized.
What information is needed for a detailed waste heat boiler quotation?
More complete process data supports a more detailed technical and commercial review. Please provide:
Process Data (Critical):
- • Gas temperature (inlet/outlet target)
- • Gas flow rate (Nm³/h or kg/h)
- • Gas composition (O₂, CO₂, SO₂, NOₓ)
- • Dust content (mg/Nm³)
Steam & Site Data:
- • Required steam pressure and temperature
- • Feedwater temperature and quality
- • Available space and height limits
- • Design code (ASME, EN, GB, or other agreed project requirements)
With limited data, ORL can first confirm whether a preliminary review is feasible and identify the information still required for a technical and commercial proposal.
