Abstract
Flue gases from a glass-melting furnace, after passing through an elevated recuperator, descend through a vertical cooling column into a horizontal convective boiler before being exhausted into a smokestack. Entering water, circulating essentially in counterflow to the flue gases, is preheated in an exit compartment of the boiler and passes via a flow regulator into the main boiler chamber and thence into a bank of vertical pipes on the periphery of the column. On rising through these pipes, the water is partly converted to steam which is superheated in an entrance compartment of the boiler before being fed to a load, the remaining water being returned to the boiler chamber.
Claims6
A steam generator utilizing waste heat from a source of flue gases, provided with a recuperator traversed by said flue gases at an elevated level above ground, comprising:
- a cooling column with an upper inlet connected to said recuperator for receiving hot flue gases therefrom, said column being provided with a bank of generally vertical pipes abstracting heat from said flue gases and being further provided with a lower outlet for said flue gases;
- a convective boiler disposed at ground level and provided with an entrance end connected to said outlet and with an exit end communicating with a chimney;
- a supply of cooling water;
- and
- conduit means including said bank of pipes for consecutively carrying said cooling water from said supply through said boiler and said column in counterflow to said flue gases and for passing resulting steam to a load.
