Diligent Micro Controls manufactures Mono-block Gas Burner. Diligent Micro Controls offers Electronic Controllers, Electronic Control Systems & Electronic Control Relays for specific industrial applications. The Mono-block Gas Burner has a centrifugal blower with suction damper for supplying combustion air. Cylindrical blast tube of appropriate dimensions is fixed on the discharge port of the blower. This blast tube carries assembly of gas pipe, ignition electrode and flame rod. Gas solenoid valve is installed at one end of the gas pipe where as its other end is blind and carries a specially perforated disc called "Diffuser Plate". Close to the diffuser plate and on the inner side, small holes are made along the periphery of the pipe to allow gas discharge. The gas coming out from these holes thoroughly mixes with air discharged by the blower and the mixture comes out uniformly through the diffuser plate.
When air/gas proportion is set correctly, it can be ignited by a small spark. A Single Pole electronic ignition transformer of 100% duty cycle and ignition electrode is used to produce this spark just in front of the diffuser plate. Another electrode is placed through the diffuser plate such that it makes contact with the flame to collect ions in the flame. This is called "Flame Electrode". Mono-block Gas Burner controller is used to monitor the safety interlocks such as air pressure switch and correctly switches the blower, ignition transformer and gas solenoid valve. These are available in different sizes starting from 50,000 k cal/hr to 5 lac k cal/hr. These Gas Burners can also be available with mono-block type gas solenoid valve which has two valves in series mechanically and one flow control valve. First valve is for quick acting and second valve is for slow opening.
