Abstract
A continuous flow heater has an elastic, flexible or rigid pipe (10) which is movably mounted and a heat source (6). When a liquid flowing through the pipe is heated in the pipe interior (1), undesired scale tends to be deposited on the interior of the pipe walls. To prevent or remove this deposit, the pipe (10) is moved and/or deformed by an internal overpressure or by application of external forces, causing the deposits to be detached from the pipe inner walls and carried away by the fluid flow. The overall pipe (10) can have an inner pipe (2), inner insulating layers (3-5), a filament (6) and external insulating layers (7-9).
Claims16
A continuous flow heater for heating a liquid comprising the combination of
- a pipe through which a liquid can flow, said pipe being elastically deformable;
- a heat source for heating liquid in said pipe, whereby deposits from said liquid form on an interior surface of said pipe;
- and
- means for elastically deforming said pipe sufficiently to cause said deposits to fragment and separate from said interior surface and to inhibit formation of said deposits.
