Product Overview Combustion Technology ©DURAG GROUP smart solutions for combustion and environment

DURAG combustion technology (1) Large-scale power plant The DURAG GROUP’s products support all types of industrial combustion processes throughout the world. These include, for example, fossil fuel power stations, plants in the chemical industry, refineries, cement plants, waste incinerators, steam generators, thermal power plants and gas turbines. We can also provide solutions for applications in special environments, such as extreme climatic zones or hazardous areas. Chemical process combustion (4) Waste gas heat treatment Rotary kiln

Flame sensor Flame monitor Compact flame monitor Industrial combustion Igniting Burner control Display module Ignition transformer Igniters Ignition lances ©DURAG GROUP Flame monitoring Ionisation detection The monitoring of the flame is a safety engineering element for industrial combustion technology – fuel may only enter the combustion chamber if safe combustion is guaranteed. Therefore high demands are made on the availability and safety of the equipment used. For intermittent operation it is sufficient when the flame monitoring hardware performs a self test during the startup...
