A boiler liner intended for improvement of combustion, reduction of smoke loss, and procurement of heat flow in existing oil- or gas-fired central heating boilers, through which the supplied heat energy is better utilized, in that by way of heat resistant material (2, 3, 6, 7, 8) the name room is upwardly confined as compared with an existing larger boiler chamber. It is according to the invention proposed that the flame limitations are designed from a highly insulating material. The high insulating capacity of the applied material will cause that the assimiluated heat is stored at temperatures almost equalling the name temperature, which will bring about that the stored volume of heat will be quickly given off by radiation after the name has been extinguished. At the same time the undesirable heat convection in the boiler chamber will fail to manifest, which in case of known flame limitations is intensified by the presence of good heat conducters and/or heat absorbing bricks. The counterradiation from the highly insulated material will cause that the interval between the sparks will be prolonged. |
