Fuel
Natural gas, special gases and blends
Fuel composition directly affects flame stability, safety logic and the best burner architecture for the project.
Solutions and applications
Industrial burners for boilers, utilities and thermal processes that demand operating stability.
FRELSER manufactures industrial burners from 0.8 MW (800 kW) to 40 MW, with custom designs for boilers, furnaces, dryers and thermal fluid heaters. Selection depends on the fuel and application conditions. We serve projects in Brazil and Latin America. SF range up to 113 MW, on request.
UNNOX burner installed on thermal equipment.
Solutions and applications
What drives industrial burner specification
Application
Boiler, process heater or utility system
The equipment type defines the operating range, mechanical access, turndown and instrumentation strategy.
Control
Burner and panel must be treated as one system
Combustion performance and maintenance quality improve when burner, controls and safety are designed together.
Burner for a molten salt heater
FRELSER burner manufactured for a molten salt heater, with combustion air at 200 °C and an internal ceramic fibre lining.
Burner ranges
SF
Industrial burner particularly suited to water-tube boilers. Models up to 113 MW, on request. Low NOx through staged combustion and a Hot Standby option, subject to design.
