Title: Electrode type water boilers
IPC: F24H1/10
Filed: 1948-11-22
Abstract: 647,631. Automatic control systems for water heaters. TATEM, J. A., and G. W. B. ELECTRIC FURNACES, Ltd. Nov. 22, 1948, No. 30317. [Class 38 (iv)] [Also in Groups XI and XXIX] An electrode type water boiler which avoids heavy loading of the power supply at the moment of switching on comprises movable insulating shields 7, 7a between pairs of electrodes 4, 6; 4a, 6a, the shields dropping between the electrodes due to heavy plate 8 when the power supply is off, and being raised to a predetermined exposing position by hydraulic means when the power supply is switched on. Upon closing manual breakers 19 and with the water temperature such that the thermostatic switch 17 operates, the contactor 18 makes, causing power supply to the electrodes, magnetic valve 14 and pump 25 to be switched on. Valve 14 is thus closed and the pump causes piston 10 and hence the shields 7, 7a to rise. Rheostat 22 shunted across the relay 21 operating winding varies the relay sensitivity to loads in the power supply and hence loads at which pump motor cut-off relay 23 operates. When contactor 18 opens due to operation of the thermostat 17 or breaker 19, the valve 14 opens, allowing liquid beneath the piston 10 to flow into reservoir 13 and the shields 7, 7a to drop.

Abstract: 1,047,695. Composite steam boilers. MARU. ZEN IRON WORKS Ltd. Aug. 2, 1963, No. 30743/63. Heading F4A. A combined convection circulation and forced recirculation boiler comprises main and subcombustion chambers 4, 5 disposed in a common box-like casing 1 and separated except at their rear ends by a vertical partition wall 6 so that gases generated by an oil burner located in a wind-box at the front end of the main chamber flow serially through the chambers. The main chamber is lined with generating tubes 9 extending between a lower header 8 and a steam and water drum 7, unheated downcomers 9<SP>1</SP> conveying water from the drum to the header in a natural circulation. The sub-chamber 5 contains a number of spirally-wound, vertically disposed tube platens 14, 14<SP>1</SP> disposed in vertically staggered relationship, the coils 14, 14<SP>1</SP> being respectively serially connected to give two continuous flow paths for the working medium which are parallel-connected between a: circulating pump and the drum 7. The pump draws water from the drum and forces it through the tube coils so that a forced recirculation is established in the sub-chamber tubes. Combustion gases which flow sinuously through the sub-chamber around vertical baffles 13 pass upwardly therefrom into a turning chamber 23 and then rearwardly through a bank of tubes 24 to a stack 26. A forced draught fan forces air for combustion over the tubes 24 to the windbox, vertical baffles 28 causing the air to flow sinuously over the tubes.

[Also in Group XXVIII] A temperature-control system for a chamber 10 comprises a reservoir 6 of low temperature liquefied gas, a pipe 8 leading from below the surface of the liquefied gas to the chamber, a source 1 of gas under pressure connected to the reservoir by a pipe 5 ending above the liquid and a continuously variable thermostat 11 responsive to the temperature of the chamber controlling the pressure of the gas applied to the reservoir. As shown, the thermostat comprises a jacket 12 containing an expansion rod 13 controlling a valve 14. If, e.g. the temperature in the chamber rises, the valve 14 tends to close, thus restricting the amount of gas which can be vented at 16 and increasing the pressure of the gas in pipe 5. This causes more liquefled gas to be forced up the pipe 8 into serpentine heat-exchanger 9 where it evaporates to cool the chamber. In a modification, the thermostat-controlled valve is located in the pipe 5.
