A roller including a roller body in a cylindrical form. The roller body comprises at least partially of a borosilicate glass material.

Roller

The gas-fired heater, especially a water heater, has an atmospheric gas burner () arranged within a nearly or completely closed combustion chamber () and associated with a premixing gas/air supply system () with a fuel gas feed nozzle (). In order to avoid oscillations, which lead to sound waves and combustion instabilities, an oscillation-damping air supply chamber (&#x2033;) is connected to the entrance () of the gas/air supply system () for combustion air, within which the fuel gas feed nozzle is arranged. The air supply chamber (&#x2033;) is provided with at least one air entrance (&#x2033;). The air supply chamber can be box-like, duct-like embracing or extending around the combustion chamber or it can be a pipe with different diameter pipe sections.

Gas-fired heating apparatus

A gas burner has a perforated, hollow body around and defining a combustion chamber. Gaseous fuel is fed to one side of the body, combustion occurs on the other side and the perforations provide a spatial connection between the fuel feed side and the combustion side. The new burner reduces exhaust gas emissions and offers a wide range of performance in the amount of heat energy provided, in the permissible range of gas pressure and in the range of fuels and fuel/air mixtures that can be used with it.
