Combustion system

A combustion system (100), comprising:

• a combustion chamber (102) having a catalyst bed (104);
• a vessel (106) for storing a propellant at a predefined pressure, the vessel (106) comprises:
• a first valve (112) for controlling a flow of the propellant over the catalyst bed (104) inside the combustion chamber (102);
• and
• a shower head injector (302) provided at the first valve (112), for injecting the propellant inside the combustion chamber (102), at a predefined duration of injection for each cycle of injection, wherein a predefined quantity of the propellant is injected in each cycle of the injection;
• the shower head injector (302) provided at the first valve (112) for enabling a uniform distribution of the propellant on the catalyst bed (104), wherein the shower injector is placed adjacent to the catalyst bed (104) such that such that there is no propellant accumulation zone between the shower head injector (302) and the catalyst bed (104);
• one or more glow plugs (108) for maintaining a predefined temperature within the catalyst bed (104);
• and
• an ignition glow plug (110) for providing a source of ignition for combustion of the fuel solution inside the combustion chamber (102), wherein the predefined duration of injection comprises a range of 70 ms to 85 ms, and wherein the predefined quantity of propellant comprises a range of 5 gm to 6 gm per injection cycle and the injector has 4 holes distributed uniformly on a PCD (pitch circle diameter) of 16 mm to 25 mm or 45% to 55% of the diameter of catalyst bed (104) for uniform distribution of the propellant on surface of the catalyst bed (104).
