CGE Double Deck Sanitaryware Kiln
The CGE Double Deck Kiln can be offered in Bogie Hearth or Moving Hood design. In either case each hearth has a sub deck and two ware support decks designed to minimise thermal mass and maintain adequate strength. Available kiln capacities include 125, 280, 400 and 600 pieces per firing. Benefits include :-* Fires both once fire and refire sanitaryware in only 11.5 hours from cold to cold. * Incorporates multi-zone control in upto 12 separate zones and is equipped with 'operator friendly' touch screen control. * Exceptional yields have been achieved in recent installations, including an average first fire yield of 85%. * CGE's unique and patented hydralift system combines both compression and labyrinth sealing to provide an excellent kiln to hearth seal, while the kiln to car and car to car sealing arrangement ensures minimum heat loss whilst maintaining outstanding temperature uniformity. * Kiln temperatures within 5 degrees C. * Minimal dunting owing to underdeck and overdeck product firing.
The choice of underdeck firing is based on the theory that the setting deck will act as a sink from which energy will be transferred to the ware. In this way, flame impingement on the ware, which creates higher temperature differentials, is avoided. CGE believe the use of underdeck firing eliminates the problem of dunting and this directly improves the overall process yield. Effective temperature control is a critical factor in providing fast, even firing and thus good quality products. CGE has developed a number of temperature control systems based on zone or individual burner control. The temperature of the kiln is controlled individually by modulating the burners in each zone. Each zone is controlled from its own thermocouple, which sends a signal to the system.
