Safety System for Heaters : (Similar to MIs Invalco/Natco Stock No. 48362445) low Temperature Shut Down Device

Introduction
Low temperature shut down device is basically PilotBurner shut offsystem. The pilot Burner helps to light the main burner. In case pilot Burner is shut, the main burner will not light and this will cause accumulation of Gas in the vessel. There can be backfiring when operator lights the main burner. To avoid this situation, pilot Burner shut off system with alarm and gas shut down valve is used which consists of following :

Pilot Burner with Gas Regulator. Model-l 000/1
This is a standard burner which is used to light the main burner as per Fig. 2. This consists of mixer (B) anp adjustable orifice (C).This is supplied with pilot (Fig.3) which houses the sensing element of low temperature Switch. The gas to the pilot burner is supplied by a W' regulator Model 400x (Fig. 4 on page 2).
Low Temperature Switch. Model 1100/5
This consists of mercury bulb with capillary tube. (Refer Fig. 5, on Page 2).The mercury in the bulb expands with rise in temperature, which extends piston stem connected on the other side of mercury bulb. The stem is connected to the knob of micro valve through linkage. The air (output pressure) at the output port of the micro valve is Zero when the burner is OFF or Maximum when the burner is ON. The sensing element of low temperature switch is housed in thermowell welded on pilot (Figure 3) for sensing temperature of pilot burner flame.
Panel for pneumatic alarm and Auto/Manual Switch Model-1100/3
The Panel consists of following

(3a) Auto/Manual Switch
During normal condition, switch is at AUTO. When pilot burner goes off the horn starts blowing. The switch is shifted to MANUAL to avoid continuous blowing of horn.
(3b) Panel Indicator
This indicator indicates 0% (OFF) when the burner is off and shows 100% (ON) when the burner is on.
(3c) Horn
The pneumatic horn blows when pilot burner extinguishes.

Gas Shut Off Valve
Model 11 00-1 (Fig.6) Similar to Natco / Invalco Model No DSG - 101B- 468) When the burner extinguishes, horn starts blowing and emergency shut off value (Fig.6) closes which stops entry of gas to the main burner.
