Filed:

Dec 17, 2001

Appl. No.:

10/024086

Assignee:

Aqua-Chem, Inc. - Milwaukee WI

International Classification:

F22D 100

US Classification:

122 7R, 122 311, 165166

Abstract:

An exhaust gas heat recuperation system for use with a boiler is disclosed. The heat recuperation system includes a plate-type heat exchanger for exhaust gas heat recovery for exchanging heat between an exhaust gas and a charge gas. The heat exchanger preferably includes a series of exhaust gas plates stacked alternately with, and parallel to, a series of charge gas plates. Each of the exhaust gas plates and charge gas plates have raised contained ridges to form a substantially sinusoidal path for directing the respective gas therealong. The shape of the path reduces exhaust gas particulate deposition. The charge gas flows in a countercurrent to the exhaust gas to facilitate maximum heat transfer. The heat exchange is particularly useful in laminar flow conditions. In one embodiment, the heat exchanger is connected to exhaust gas inlet and outlet conduits, change gas inlet and outlet conduits, and a condensate collection changer as part of an exhaust gas heat recuperation system, for use particularly in steam or hot water boiler applications.

F24D 3/02

US Classification:

237 8 A, 1224483, 237 81, 700300

Abstract:

Hydronic heating systems, controllers for such systems, and methods of using/operating same are disclosed herein. In one example embodiment, such a system includes at least one condensing boiler and at least one non-condensing boiler, and at least one controller configured for utilizing at least one PID control program to generate at least one signal for controlling firing rates of one or more of the boilers based upon sensed water temperature and temperature setpoint inputs. Depending upon the mode of operation, the at least one PID control program is a first PID control program dedicated to controlling only the at least one condensing boiler, or is a second PID control program dedicated to controlling only the at least one non-condensing boiler, or includes both the first and second PID control programs. Also, outside air temperature serves as a basis for generating the temperature setpoint inputs.
