Jumag waste heat boilers use hot exhaust gas from an upstream process for creating steam.
Jumag waste heat boilers: Compact, efficient, robust, modular, no monitoring in many countries.
OVERVIEW
HIGH HEAT EXCHANGE PERFORMANCE ON A COMPACT AREA
MODULAR DESIGN – COST EFFECTIVE ADAPTATION TO DIFFERENT REQUIREMENTS
NO MOT MONITORING - NO BOILER ATTENDANT IN MANY COUNTRIES
EASY TO OPERATE – USER FRIENDLY
ROBUST VAPORISATION SYSTEM IN THE FORM OF A SMALL SHELL BOILER
ADVANTAGES
ECONOMICAL

Available as compact steam system including blow down unit and water treatment unit
THE FUNCTIONING
Basic equipment for the waste heat boiler includes:
Double-walled pressure element in the form of a small shell boiler
Low-maintenance centrifugal pump
Intuitive touch-screen controls
Integrated switch cabinet
In addition to the instructions for related safety components: Safety valve, over-pressure off switch, overheating shutdown exhaust, overheating shut-off for steam, low water cut-off switch, pump pressure monitoring, ...
The exhaust gases are introduced from above in the boiler.
Depending on the water level in the pressure vessel, the feed water is replenished by means of the boiler pump via the economiser into the pressure vessel.
The burner is controlled depending on the steam pressure. Via multiple pass flue-gas routing, the heat transfer takes place through the pressure vessel on the water.
In the economiser additional heat is transferred from the flue gas to the fresh water in a counter current. In the inner part of the pressure vessel the steam is dried.
