BURNER HEAD

The Auto Switch Dual Fuel Burners embody the best features of both Gas and Oil Burners. The Burner is Supplied with a dual gas and oil combustion head giving the burner the capability of firing on either fuel. The burner management system to change from one fuel to another is operated by a switch. The oil combustion head is an advanced design of flame plate with accurate adjustment for centering of nozzles and electrodes etc. The gas combustion head is advanced design utilizing staged mixing and turbulence. A stainless steel convergent flame tube gives accurate flame shape control through maximum use of saving energy and axial aerodynamic head loss adjustment.

OIL PUMPING UNIT

An Oil pumping unit supplies the oil to the burner at the preset pressure for the automization of fuel oil, A heater is incorporated along with circulation system in case of furnace oil application. A filter precedes the pump for the filtering of fuel

GAS TRAIN

A Gas train properly sized for minimum pressure loss comprises of Main shut off ball valve, Gas filters, Gas pressure switch, Secondary Stage pressure regulators, Press gauges, Safety gas solenoid valves, Orifice valve, Slow opening motorized gas valve works as the gas supply to the burner in set and safe mode.

CONTROL PANEL

An Electrical control panel prewired with the electrical components for the blower, oil pump, etc. A Fuel Changeover switch changes the fuel from oil to gas and vice versa. An U V Based sequence controller works as the automatic system of the burner. A flame failure safety alarm is energized in case of any abnormality of flame.

An U V Cell supervises the oil and gas flame and operates the burner in safe condition.

LAP Burners has been designed to operate & burn light & heavy grades of fuel oils using only low pressure air and oil. Perfect oil atomisation is obtained without the use of compressed air or high pressure oil. The heavy oil needs to be preheated to obtain the correct viscosity before being passed through the burner. 

Excellent flame stability is achieved throughout the burner output range.  The construction of the burner is robust with cast iron bodies giving them durability in the high temperature operations.  The burners are supplied in various capacity ranging from 10-100 lph.
