Abstract
The invention relates to apparatus for carrying out physical and/or chemical processes, more specifically a heat exchanger (10) of the continuous type, comprising a large number of vertical heat exchanger tubes (18) mounted between a lower chamber (17) and an upper chamber (16) within a jacket (15). Within the tubes (18) small solid particles are kept in a fluidized condition by the fluid medium passing up from the lower chamber (17) through the tubes (18), so as to achieve a good heat transfer, whereas also any deposit will be removed from the inner tube walls. For the downward flow of the granular mass at least one return tube (21) is provided. Downward circulation of the fluid medium through the return tube (21) should be minimal. To stabilize the fluid bed in a riser tube the inflow pipe is provided with a lateral bore (23) and the top of the lower chamber above the level of the lateral bores (23) is fitted with an outlet 51 with a shutoff valve 52 to temporarily reduce pressure of the fluid medium at the top of the lower chamber should the lateral bores become clogged.
