Product Description

1.        Applications

This line is for leather coating, also for similar products drying.

2.        Characteristic

Currently for leather drying, most processes adopt electricity heating system, our lines adopt gas-fired infrared heating system, which can greatly reduce not only the energy cost but also the drying shrinkage of leather.

4.        System Components

A.      Metal fiber burner

l Each unit has two rows of burner, 2 burners per row, maximum capacity is *2kw, maximum gas consumption is 4m3/h.

l High radiation efficiency：Heat is transferred to the leather by radiation rapidly and easily.

l Homogeneous combustion：The combustion is homogeneous along the width, ensure drying leather evenly.

l Good flashback resistance: special structure for full-premixed burner avoids flame flash-back.

l Low thermal inertia: burner surface temperature can drop down to room temperature in several seconds while the system stopped, which makes it can effectively prevent fire accidents caused by power break.

B.       Furnace

l Adopt built-up structure, easy to assemble and maintenance.

l Multi-angle stainless reflector: reflect infrared ray back to the leather surface.

l Covered by heat insulator: low thermal conductivity, low temperature on outside surface and low thermal loss.

C.       Control system

l The core of the control system is PLC and touch screen, the whole system is controlled by PLC, related parameters are set and displayed on the touch screen.

l System functions: pre-purge, automatic ignition, flame detection, protection and alarm for flame failure, low pressure protection for gas and air.

l PID heat adjustment mode: The capacity of the burner is adjusted by PLC automatically.

l Photoelectric detection system: If the leather is not detected by the system, the heat load will be adjusted to low level even cut off automatically.

l Exhaust system: accuracy control air exhaust according to the humidity detection.
