US Patent:

44898827, Dec 25, 1984

Filed:

Mar 4, 1983

Appl. No.:

6/472419

Inventors:

Larry C. Rodgers - Circle Pines MN

Assignee:

Honeywell Inc. - Minneapolis MN

International Classification:

F24F 314

US Classification:

236 78D

Abstract:

A thermostat uses a source of a signal representing anticipation heat which is transmitted to a circuit to be combined with a signal from a temperature sensing element with a first time constant or delay when the thermostat is "ON", i. e. , controlling a heat source to supply heat to a heat receiver and with a different time constant or delay when the thermostat is "OFF", i. e. , controlling the heat source to interrupt the supply of heat to the heat receiver. This variable time constant provides a greater proportion of the anticipation or feedback of the anticipation signal to be combined with the signal from the temperature sensing element circuit at light loads of the temperature or heat producing element in the heat source to improve the stability of the heat control system since stability is generally increased with increased feedback without increasing the total anticipation heat representing signal whereby to minimize the system control point offset or droop which is the control band in which the control action of the thermostat takes place between the start of the "on" operation and the full "on" operation.

Abstract:

A burner having lower emissions and lower unburned fuel losses by implementing a transition zone in a low NO. sub. x burner. The improved burner includes a pulverized fuel transport nozzle surrounded by the transition zone which shields the central oxygen-lean fuel devolatilization zone from the swirling secondary combustion air. The transition zone acts as a buffer between the primary and the secondary air streams to improve the control of near-burner mixing and flame stability by providing limited recirculation regions between primary and secondary air streams. These limited recirculation regions transport evolved NO. sub. x back towards the oxygen-lean fuel pyrolysis zone for reduction to molecular nitrogen. Alternate embodiments include natural gas and fuel oil firing.

International Classification:

B03C 302

US Classification:

55139

Abstract:

A shorting and test mechanism for an electrostatic air cleaner uses an electrically conductive spring element attached to an access door to the air cleaner whereby an opening movement of the door effects a motion of the spring to contact the high voltage electrode support assembly to discharge any residual electrical charge on the high voltage assembly to ground. Conversely, the closing of the access door forces the spring away from the high voltage electrode assembly to permit a normal operation of the air cleaner. The spring is further connected to an electrically insulating test button located in an opening in the access door to induce by an operator a selective motion of the spring toward the high voltage electrode assembly whereby to test for the existence of the high voltage on the electrode assembly by providing an electrical arc path to ground through the spring when the test button is depressed.
