Abstract
The invention refers to a method for low-emission, non-catalytic combustion of a liquid fuel consisting of the following steps: separate introduction of the liquid fuel in a non-ignitable state into a mixing zone, vaporization of the liquid fuel in the mixing zone, separate introduction of a gaseous oxidizing agent into the mixing zone, mixing the fuel and the gaseous oxidizing agent in the mixing zone so that an ignitable mixture is created, wherein the mixing zone is formed so that combustion is not possible even when the ignition temperature of the mixture is reached within the mixing zone, and combustion of the mixture in a combustion zone located down current from the mixing zone.

Method for low-emission, non-catalytic combustion of a liquid fuel consisting of the following steps:
- 1.1 separate introduction of the liquid fuel in a non-ignitable state into a mixing zone,
- 1.2 vaporization of the liquid fuel in the mixing zone,
- 1.3 separate introduction of a gaseous oxidizing agent into the mixing zone,
- 1.4 mixing the fuel and the gaseous oxidizing agent in the mixing zone so that an ignitable mixture is created, wherein the mixing zone is formed so that combustion is not possible even when the ignition temperature of the mixture is reached within the mixing zone, and
- 1.5 combustion of the mixture in a combustion zone located down current from the mixing zone.
Method for low-emission, non-catalytic combustion of a liquid fuel consisting of the following steps:
- 2.1 vaporization of the liquid fuel in a vaporizer,
- 2.2 separate introduction of the vaporized fuel in a non-ignitable state into a mixing zone located down current from the vaporizer,
- 2.3 separate introduction of a gaseous oxidizing agent into the mixing zone,
- 2.4 mixing the fuel and the gaseous oxidizing agent in the mixing zone so that an ignitable mixture is formed, wherein the mixing zone is formed so that combustion is not possible even when the ignition temperature of the mixture is reached within the mixing zone, and
- 2.5 combustion of the mixture in a combustion zone located down current from the mixing zone.
Method as defined in one of the preceding claims, wherein the mixture is fed to a second porous element which forms the combustion zone and is burned in its pore volume under formation of a flame.
Method as defined in one of the preceding claims, wherein the first and the second porous element are arranged lying directly next to each other.
Method as defined in one of the preceding claims, wherein the perforated plate and/or the first and/or second porous element is/are made of a ceramic.
Method as defined in one of the preceding claims, wherein the mass flow of the fuel fed to the mixing zone and/or the mass flow of the gaseous oxidizing agent is/are controlled.
Method as defined in one of the preceding claims, wherein the fuel and/or the gaseous oxidizing agent is/are preheated.
Device for low-emission, non-catalytic combustion of a liquid fuel with a mixing zone and a combustion zone located down current from the mixing zone, wherein connected with the mixing zone are a means for separate introduction of the liquid or vaporized fuel in a non-ignitable state and a means for separate introduction of a gaseous oxidizing agent, and wherein the mixing zone is formed so that combustion is not possible even when the ignition temperature of the mixture is reached within the mixing zone.
