Engineering FAQs

Waste Heat Boiler Technical Questions

Comprehensive answers to the most frequently asked questions by plant managers, energy engineers, and EPC contractors

Which process gases can your waste heat boilers handle?

Our waste heat boilers are designed for a wide range of clean and dust-laden flue gases from various industrial processes:

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 Considerations: We handle various gas compositions including SO₂, NOₓ, dust content up to 50 g/Nm³, and corrosive components with appropriate material selection and protective measures.

How do you select the optimal boiler configuration?

Boiler type and layout selection is based on comprehensive analysis of process conditions and site constraints:

1
Thermal Analysis

Gas flow rate, temperature profile, heat transfer calculations, and steam parameters optimization

2
Mechanical Design

Pressure drop limitations, structural support, thermal expansion, and maintenance accessibility

3
Site Integration

Available space, transportation constraints, existing infrastructure, and installation requirements

Configuration Options: Vertical/horizontal natural circulation, fire tube/water tube arrangements, modular sections for transport, and hybrid designs for complex applications.

What design features improve efficiency and reliability?

Our advanced design features focus on maximizing heat recovery while ensuring long-term operational reliability:
