Romantic for some, annoying for others – the smell of a wood fire is perceived differently. Unpleasant odours are usually caused by incorrect operation or the burning of unsuitable fuel. However, even when used correctly, a typical ‘fireplace smell’ can be detected in the surrounding area. This is partly due to what are known as […]
When wood is burned, flue gas is produced.This process is physically determined and can only be influenced to a limited extent.An electrostatic precipitator can filter the most harmful solids from the flue gas.The burning of natural wood (untreated, unprocessed) produces dust consisting of minerals, soot and tars.An efficient fireplace that meets modern standards can reduce […]
Dust collectors are usually passive filters such as yarns, membranes, foam ceramics or other fabrics.They retain the dust in the exhaust gas and trap it in the filter.This is why these filters, like catalytic converters, need to be replaced or cleaned regularly.In some cases, it is necessary to install a fan, as the filters can […]
Catalytic converters reduce, among other things, the so-called organic particles that make up soot and tar. They contribute to the formation of less fine dust, but retain fewer particles than electrostatic precipitators. Their main task is therefore not to remove particles from the exhaust gas, but to remove other toxic substances. As a side effect, […]
Yes, in addition to electrostatic dust collectors, catalytic and filter dust collectors are also common. Catalysts and filter separators reduce the diameter of the chimney or reduce the chimney draught due to their design. Electrostatic precipitators reduce the chimney diameter, albeit slightly, and have very little effect on draught conditions.
Yes, they are also known as electrostatic precipitators, electrostatic filters, electrostatics or particle separators. There are also devices that are simply called dust collectors. It is important to check whether they actually work with an electrostatic field or whether they are so-called passive filters.
The performance of different technologies can be compared using what is known as collection efficiency. Separation efficiency can be measured in two ways. Either you weigh the particles retained by the collector, or you count them.Both methods have their advantages and disadvantages. Weighing is currently (2024) the most commonly used method for regulatory approval or […]
An electrostatic precipitator can remove a large proportion of particles from the exhaust gas. If the efficiency is measured by the number of particles, then on average across all manufacturers, over 90% of the particles are removed electrostatically, and around 70% by mass. Separators for stoves and tiled stoves, which do not work electrostatically, usually […]
