Lühike sissejuhatus
Aurukatel on keemiatööstuse tootmisel oluline seade.
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 katla toru.
Hiina katlad jagunevad elukateldeks, üldtööstuskateldeks, vedurikateldeks ja söeküttel töötavateks kateldeks.
