Product introduction of flameout protection device for trolley-type resistance furnace
Flameout protection is very important and can detect whether the flame in the burner is extinguished. When the ignition flame or main flame is extinguished, the trolley type resistance furnace flameout protection device can cut off the gas gas path, prevent gas from leaking out, avoid accidents, and ensure safety. In addition, it can also protect when the ignition is not on or when it cannot be ignited in time.

Flame detection elements of flameout protection devices can be divided into three categories: light-sensitive, heat-sensitive and conductive. Flameout protection devices include bimetallic, thermoelectric, flame-conducting, photocell, and aluminum silicide flameout protection devices: gas-fired boilers and industrial furnaces almost use photosensitive components. pph ball valve, pvdf tube is the most commonly used UV photocell flameout protection device.

The gas safety control system is mainly composed of flame detectors, gas shutoff valves and fans.

When heating in a continuous furnace, the workpiece is moved. The most common continuous furnaces are linear end discharge continuous furnaces and side discharge continuous furnaces.

The hearth of some trolley-type resistance furnaces is made fixed to allow the workpiece to move on the hearth; some furnaces have the hearth itself made movable.

When the fixed furnace bottom is adopted, the workpiece can be moved downward by the inclined slide rail or roller table by gravity, or it can be pushed through the furnace by the pushing mechanism. The end discharge continuous furnace is a furnace that discharges by gravity.

Rotary-bottom type or rotary-type continuous furnaces and trolley-type furnaces are movable Shanghai-type bottom furnaces, which are widely used. The workpiece of the rotary furnace is placed on the rotary table, and it is taken out after the table has not been rotated for a week.

The trolley-type resistance furnace stays in the furnace while heating and cooling the workpiece. Only when loading and unloading, the trolley moves outside Shanghai. The trolley furnace is mainly used for heating large or heavy workpieces.
