External Heating Structure and No Direct Contact with Flame

HY-G series external heating furnace takes gas (natural gas, LPG, combustible gas and bigas) as heat source. Gas will be burnt in heating chamber and heat will be transferred to rotary kiln shell through radiation, conduction and convection. Materials will not directly contact with flue gas or flame. Whole working process consumes less energy and holds high safety level.

Ratio-regulating Burner Adjust Working Temperature Smoothly

HY-G furnace is suitable for large scale continuous production line. Heat source part is controlled by switch-button control cabinet or PLC. There are multi-groups of burner adopting ratio-regulating. Working temperature and heat can be smoothly adjusted. According to production process, specific working temperature and calcining time can be flexibly adjusted.

Less Quick Wear Parts and Easy Maintain

Heating chamber adopts two-stage assembly design which provides convenience for maintenance and disassembly. Superior heating components holds longer service life. There are various layout mode available, parallel type, side-mounted type and drawer-type, easy to replace and less malfunction point. It is a representative for Hengyang's effort for humanization design.

Closed Working System and No Pollution

Hengyang HY-G furnace is indirect heating rotary furnace where materials move in inner tube. Indirect heat transfer and closed system causes no pollution to environment and prevents pollution caused to materials. It holds high recycling rate and causes less impurities to final product.

Automatic Control and Require Less Labor Force

Feeding silo and feeder adopt instant speed control so that to guarantee continuous operation. It adopts multiple-temperature and multiple pressure point supervision. Blower, induced draft fan, protection gas openness and pressure can be automatically controlled. No need paper recording makes easy transition for working shifts.

Scientific Design Layout Guarantees Reliable Operation

Furnace door of burner adopts quick-open structure and there is observation window and inspection door set at both sides of combustion room, which provides convenience for supervising external heating running status. It can be designed into both single body heating zone and multi-chamber heating zone divided by fire-proof modular. Hengyang HY-G furnace makes it come true to realize multiple temperature process curve in one single body.
