Definitions
- the technical field also relates to that of a process for improving the conditions of domestic wood heating using a pellet stove.
- Wood pellet stoves are high-performance and eco-friendly heating devices when they are properly adjusted and powered.
- ISO 17225-2 standard or the EN 14961-2 standard which define certain windows of technical characteristics of the pellets produced, such as the density of the pellets or pellets, the durability, the calorific value, the melting temperature of the ashes. , their moisture content or the origin of the wood used. Given the significant variability of the characteristics of the raw material entering the factories, all of these parameters allow an almost infinite number of combinations.
- An oxygen sensor and possibly a carbon monoxide sensor, also commonly called a Lambda sensor in the field, is a small sensor located in the flue gas outlet, at the boiler gas outlet. This probe measures the proportion of air and fuel in the unburned gases following combustion in a wood boiler.
- the oxygen sensor and possibly the carbon monoxide sensor, is intended to identify combustion errors, in particular the oxygen level.
- a calculator or a boiler control automaton varies the primary and secondary air flow rates and the fuel flow rate almost in real time, maintaining maximum efficiency despite variations in power demand or fuel quality (density, humidity, ash, etc.).
- pellet stoves do not include this oxygen sensor, and possibly carbon monoxide sensor, which is too expensive, it is known, during installation, that a professional installer proceeds to a precise adjustment of the flow rates of primary and possibly secondary air and the flow of pellets in the stove. This adjustment work guarantees the user of the domestic pellet stove performance and emissions of particles, nitrogen oxides, carbon monoxide, and other gases as provided by the manufacturer. To do this, the professional installer uses a mobile installation comprising specific and expensive probes. This intervention should be done when the pellet stove is installed, but most often installers leave the factory settings.
