Kort inleiding
Stoomketel is 'n belangrike toerusting vir die vervaardiging van chemiese industrie.
The steam is an indispensable source of heat source and power source in petrochemical enterprises. With the development of production technology, the exchange and recycling of heat energy is becoming more and more frequent, and the use of various types of boilers is increasing, so the automation of boiler operation is becoming more and more attention. Boiler operation automation not only reduces the labor intensity of workers, to ensure the safe and stable operation of equipment, more important is greatly improve the efficiency of fuel combustion, has good effect to save energy. In this case, we must understand the purpose and characteristics of the stainless ketel buis.
China se ketels word verdeel in lewende ketels, algemene industriële ketels, lokomotiewe ketels en steenkool-aangedrewe kragketels.
