A flame tube boiler is generally a shell boiler with one or two flame tubes. Smooth or corrugated flame tubes can be used. Due to the better use of energy, the pure flame-tube boiler has developed into today's flame tube-smoke tube boiler. Smoke gases firstly flow through the flame tube and then the smoke tubes using one- or two-pass technology. The boiler water flows around the flame tube and smoke tubes.

A flame tube boiler is used wherever hot water or steam of a consistently high quality is required. As a rule, a flame-tube boiler has always a sufficient stock of steam, even during sudden usage peaks.

LOOS INTERNATIONAL builds a flame tube boiler using the tried and tested three-pass principle. They offer shell boilers as a single flame-tube or a double flame-tube boiler for steam production capacities up to 55,000 kg/h and for hot water generation up to 38,000 kW.
The various flame tube boiler plants, also known as shell boilers, are manufactured in all pressure stages and for all fuels and can be fitted if required with heat recovery systems to improve efficiency for all technical heating processes.
