Combustion Systems Matched to Your Gas Supply
Gas properties and supply conditions vary. The burner and fuel supply system must be selected to suit the actual gas source.
Oil/gas dual-fuel configurations can be evaluated where fuel switching is required. Compatible fuels and switching arrangements are defined during system design.
If gas specifications are not yet available, you can start by sharing information from your gas supplier or details of your existing supply facilities.
| Gas Source | Configuration Considerations |
|---|---|
| Pipeline natural gas / Regasified LNG | Configured according to gas supply conditions at the furnace inlet and process heating requirements |
| LPG | Burner and fuel supply configuration matched to the actual gas composition and supply arrangement |
| Industrial by-product gases and other combustible gases | Suitability assessed based on gas composition, heating value, impurities and supply stability |
Select the Heating Method for Your Process
Direct-Fired Heating
Hot combustion gases mix with dilution air to reach the required temperature before entering the dryer or process equipment. This arrangement is suitable for processes that permit contact between the material and combustion gases. Suitability depends on gas composition, material properties and product requirements concerning contact with combustion products.
Indirect Heating
Combustion gases transfer heat to process air through a heat exchanger, keeping the two gas streams separate. This arrangement is suitable where materials must not contact combustion gases or where product color, odor and process-air cleanliness are important. The heat exchanger is selected according to the required temperature, airflow and heat duty.

Process and Control
Simplified Process and Control
Direct-Fired System
Fuel Gas + Combustion Air → Combustion System → Hot Combustion Gases
Hot Combustion Gases + Dilution Air → Mixing & Temperature Adjustment → Process Hot Air → Dryer / Process Equipment
Indirect Heating System
Fuel Gas + Combustion Air → Combustion System → Hot Flue Gas → Heat Exchanger: Flue-Gas Side → Flue-Gas Exhaust System
Process Air → Heat Exchanger: Air Side → Process Hot Air → Dryer / Process Equipment
These diagrams illustrate the heating principles. Fan arrangements and airflow paths are determined during project engineering.
The control system adjusts firing rate to meet hot-air temperature requirements and coordinates combustion-air and process-air flows. Ignition, flame monitoring, gas-pressure monitoring and protective shutdown interlocks are configured to suit the combustion system and downstream equipment.

Supply Scope and Production-Line Integration
Equipment and services are configured for each project. The final scope is defined in the technical proposal and quotation.
New Installations: The heating system is matched to production requirements, with clearly defined interfaces to downstream equipment.
System Upgrades: For coal-to-gas conversion, oil-to-gas conversion or heat-source replacement, Meibao reviews the existing heat duty, airflow, system pressure drop and control interfaces to determine which equipment can be retained and what modifications are required.
Gas-fired hot air furnace supply scope and production-line integration
The inclusion of upstream gas storage, vaporization facilities, plant gas piping and downstream production equipment is clarified during the proposal stage.
Fuel Cost Estimate: Gas consumption can be estimated from heat duty, gas heating value and system efficiency, then combined with local gas prices to assess fuel costs. Estimates are based on agreed operating conditions.
| Category | Available Equipment and Services |
|---|---|
| Furnace equipment | Furnace body, burner and furnace gas valve train |
| Auxiliary systems | Fans, ductwork and control system; a heat exchanger for indirect heating |
| Project services | Design, manufacturing, installation guidance, commissioning and operator training |
Discuss Your Gas-Fired Hot Air Project
For an initial assessment, please share:
- Application: The material to be dried or heated and the equipment to be supplied with hot air.
- Production requirements: Hourly throughput, specifying feed or finished-product capacity, and the required hot-air temperature at the process-equipment inlet, if known.
- Location and gas source: Project country and available gas type.
- Project type: A new installation or an existing-system upgrade.
Further selection may require information on whether the material can contact combustion gases, airflow, operating hours and gas specifications. Drying projects also require initial and target moisture contents. Applicable local emission requirements will be reviewed. Any available information can be submitted with your initial inquiry.
Meibao will review the information, identify any additional data needed and recommend a preliminary configuration. A quotation will follow once the technical requirements are confirmed.
