Steam superheater drying
Thread Content
Before starting up the plant, the steam superheater is heated up; the drum is not in use, and steam needs to be introduced into the furnace tubes. How is the steam supplied?
Steam can be taken from the steam pipeline network; if not available, using a temporary boiler incurs higher costs. There are specialized furnace drying companies.
Steam must be discharged only through the various drain and backflow valves along the pipeline; otherwise, if steam does not reach certain sections of the pipeline, the effect of drying the furnace will be lost. As the furnace temperature rises, the external steam valves need to be adjusted regularly to prevent excessive opening that would result in waste of steam.
We all use evaporation steam ovens.
Steam is drawn from thermal piping networks or other boilers; if it is not available, steam curing cannot be used, and alternative methods must be employed.
The oven can be heated with firewood, or with an oven heater
Deoxygenated water from the deaerator can also be used for furnace drying
Steam can be used to heat ovens; we are a company that specializes in installation, maintenance, and renovation of such ovens. Wood and coal are often used for heating them, and after maintenance, the ovens are also heated using steam (we have backup boilers).
