Draught Accelerators

Draught Accelerators

Draught accelerators, also known as draft accelerators, are devices used to increase the draft in a chimney or flue system. The draft is the force that pulls combustion gases and smoke out of a building and up the chimney. Without sufficient draft, smoke and other harmful gases can accumulate in a building, leading to health hazards and even fire. Draught accelerators work by creating a pressure difference between the inside and outside of the chimney or flue. This pressure difference increases the velocity of the gases and smoke, which in turn increases the draft. There are several types of draught accelerators, including mechanical and passive devices. Mechanical draught accelerators use fans or blowers to increase the velocity of the gases and smoke. These devices are typically installed in the chimney or flue and are powered by electricity or other fuel sources. Passive draught accelerators, on the other hand, rely on natural forces such as wind to create the pressure difference needed to increase the draft. Draught accelerators are commonly used in buildings with wood-burning stoves or fireplaces, as these appliances often require a strong draft to function properly. They are also used in industrial settings, such as power plants and factories, where large amounts of smoke and gases need to be vented. Overall, draught accelerators are an important tool for ensuring the safe and efficient operation of chimneys and flue systems. By increasing the draft, they help to prevent the buildup of harmful gases and smoke in buildings, and improve the performance of appliances that rely on proper ventilation.
