Combustion furnace based on liquid ethanol-natural gas composite fuel and method thereof

Abstract

The invention discloses a combustion furnace based on liquid ethanol-natural gas composite fuel. The combustion furnace comprises a combustion furnace body, and the combustion furnace body comprises acomposite fuel combustion furnace which is of a cone-shaped circular platform structure with a thin end facing down; the lower end of the composite fuel combustion furnace is coaxially provided witha flame nozzle, and the firing direction of the flame nozzle is vertical upwards; the upper end of the composite fuel combustion furnace is a smoke exhaust wall, and the smoke exhaust wall is providedwith a plurality of smoke outlets; and the combustion furnace is simple in structure, the cone-shaped circular platform type combustion chamber is adopted and matched with an ethanol gasification cone to guide ordinary natural gas jet flames into a trumpet shape, and the flames go forwards by being attached to a heating pipe distributed in a conical spiral form, so that the heating area of the flames is enlarged.

Description

technical field [0001] The invention belongs to the field of combustion furnaces, in particular to a combustion furnace based on liquid ethanol-natural gas combined fuel and a method thereof. Background technique [0002] The heat-conducting oil boiler uses heat-conducting oil as the medium, and uses the hot oil circulating oil pump to force the medium to circulate in liquid phase, transfer the heat energy to the heat-consuming equipment and then return to the heating furnace for reheating, and deliver the heat energy to the heat-consuming equipment before returning to the heating furnace for reheating , it can obtain high working temperature under low pressure, and can carry out high-precision control work on the operation of the medium; the combustion chamber of the existing heat-conducting oil boiler is mainly composed of simple combustion-supporting air and gas mixed and sprayed into the combustion chamber, due to The normal injection flame cannot completely and evenly h...

Problems solved by technology

[0002] The heat-conducting oil boiler uses heat-conducting oil as the medium, and uses the hot oil circulating oil pump to force the medium to circulate in liquid phase, transfer the heat energy to the heat-consuming equipment and then return to the heating furnace for reheating, and deliver the heat energy to the heat-consuming equipment before returning to the heating furnace for reheating , it can obtain high working temperature under low pressure, and can carry out high-precision control work on the operation of the medium; the combustion chamber of the existing heat-conducting oil boiler is mainly composed of simple combustion-supporting air and gas mixed and sprayed into the combustion chamber, due to The normal injection flame cannot completely and evenly heat the heating tube in the existing regular cylindrical combustion chamber, resulting in full use of heat, and at the same time, some gas is not fully utilized and is discharged with the flue gas, resulting in energy waste;

[0003] At the same time, the existing combustion furnace uses a single gas fuel, but ethanol is a liquid renewable energy source. Due to the liquid property, the existing combustion furnace combustion chamber structure cannot adapt to liquid ethanol fuel.
