An alcohol fuel burner and decomposer in which one stream of fuel is preheated by passing it through an electrically heated conduit to vaporize the fuel, the fuel vapor is mixed with air, the air-fuel mixture is ignited and combusted, and the combustion gases are passed in heat exchange relationship

An alcohol fuel burner and decomposer in which one stream of fuel is preheated by passing it through an electrically heated conduit to vaporize the fuel, the fuel vapor is mixed with air, the air-fuel mixture is ignited and combusted, and the combustion gases are passed in heat exchange relationship with a conduit carrying a stream of fuel to decompose the fuel forming a fuel stream containing hydrogen gas for starting internal combustion engines, the mass flow of the combustion gas being increased as it flows in heat exchange relationship with the fuel carrying conduit, is disclosed.

An alcohol fuel burner and decomposer comprising: means for preheating at least one stream of fuel; means for mixing said preheated fuel with air; means for igniting the resulting air-fuel mixture; combustion chamber means for containing the ignited air-fuel mixture during combustion thereof; heat exchange confining means constructed and disposed to receive combustion products from the combustion chamber means in an entrance of a relatively larger size, directing the combustion products through a progressively smaller flow area to an exit of relatively smaller size, as compared with the entrance, and heat exchange conduit means in the heat exchange confining means for conducting a stream of fuel in heat exchange contact with the combustion products for heating said fuel in said conduit means to the decomposition temperature of the fuel for forming a hydrogen gas containing starter fuel stream, the heat exchange confining means and heat exchange conduit means being so constructed and configured that the mass flow rate of combustion products increases from entrance to exit and the heat exchange rate between the combustion products and the fuel in the heat exchange conduit means remains generally constant from entrance to exit.
