Multi-fuel combustion device and method

Abstract

The invention discloses a multi-fuel combustion device and a method, which belong to the field of fuel heating. A combustor in the device is connected with a control valve, a temperature sensor is connected with an electric control cabinet, a combustion chamber is communicated with the combustor and used for combusting solid fuel, the combustor is used for combusting fuel gas or fuel oil so as to heat up to-be-heated substances in a heat exchange device, and accordingly combustion of multiple fuels is realized. When air pressure in the combustion is over high or over low, the combustor is automatically flamed out, the electric control cabinet controls closing of the control valve, fuel supply to the combustor is stopped, energy waste is avoided, and the fuel supply to the combustor is automatically adjusted. When the temperature sensor displays that the temperature of the to-be-heated substances is higher than set temperature, the electric control cabinet controls the combustor to be automatically flamed out; when the temperature of the to-be-heated substances in the heat exchange device is lower than the set temperature, the electric control cabinet controls the combustor to be automatically ignited; and an automatic heat-insulation function is realized, and safe and reliable running is guaranteed.

Description

technical field [0001] The invention relates to a fuel heating device, in particular to a multi-fuel combustion device and method. Background technique [0002] At present, common hot water devices can only use a single fuel, and the structure cannot meet the needs of burning multiple fuels in the same device, especially in the vast rural areas where fuels such as natural gas and diesel are scarce or costly, while biomass fuel reserves are abundant , but the market lacks a hot water device that can use multiple fuels such as biogas, coal, natural gas, diesel oil, and biomass briquettes. Secondly, common fuel oil or gas hot water boiler products and other hot water devices on the market have a low degree of automation control, difficult maintenance, safety performance needs to be further improved, and poor energy saving and consumption reduction performance. Contents of the invention [0003] The purpose of the present invention is to provide a multi-fuel combustion device...
