The invention relates to a water heating device, comprising a burner (20) and a flame current measuring device (100) for measuring a flame current, which measuring device comprises two electrodes and a voltage source (14), wherein each of the poles (18, 19) of the voltage source is connected to one of the electrodes. The water heating device further comprises a heat exchanger (40) which is electrically insulated relative to the burner. The burner and the heat exchanger here form the electrodes of the flame current measuring device. The heat exchanger functioning as electrode can be earthed (41). The measured flame current can be used to determine the excess air factor of the combustion. The water heating device can further comprise an air/fuel controller for controlling the air/fuel ratio, wherein the air/fuel controller uses the determined excess air factor to control the air/fuel ratio. The invention also relates to a method for measuring a flame current in a flame.

The present invention relates to a control method of preventing backflow of exhaust gas of a multiboiler that is composed of a plurality of boilers connected in a line, each of which includes a wind pressure sensor measuring wind pressure of air flowing into a combustion chamber and a controller controlling the number of revolutions of a fan supplying air into the combustion chamber on the basis of the wind pressure measured by the wind pressure sensor, and in which any one of the controllers is set as a master controller and the other controllers are set as slave controllers and the master controller and the slave controllers are connected by a communication line to communicate with each other, and the control method includes: measuring wind pressures of air flowing into the combustion chambers using the wind pressure sensors in the controller of boilers that are in operation; and calculating the average wind pressure of the boilers that are in operation in response to information about the wind pressures measured by the controllers of the boilers that are in operation, using the master controller, determining the control amount of wind of the fans of boilers that are not in operation on the basis of the average wind pressure, and then operating the fan of the boilers that are not in operation on the basis of the determined results. According to the method, it is possible to provide a multi-boiler or a multi-water heater that does not generate additional cost for installing the dampers are not needed and does not substantially breakdown due even though it is used for a long period of time, thereby saving cost for maintenance.

A method controls a modulating gas furnace by monitoring a differential pressure associated with the modulating gas furnace, learning an intermediate value associated with an intermediate capacity between a minimum output capacity of the gas furnace and a maximum output capacity of the gas furnace, learning one of a high value associated with the maximum output capacity and a low value associated with a minimum output capacity, establishing an estimated operating curve using either the intermediate value and the low value or using the intermediate value and the high value, and operating the gas furnace in accordance with the estimated operating curve.
摘要:
In a multistage combustion furnace having a motor driven inducer blower and a pressure sensing device or set of switches for sensing pressure in the combustion gas flowpath through the furnace, a high firing rate blower speed and low firing rate blower speed are set based on the blower speed setting required for a medium firing rate. Each particular furnace, having its own pressures and combustion gas resistance to flow characteristics, may be provided with a database of inducer blower motor speeds required to achieve predetermined pressures in the combustion gas flowpath for a variety of combustion gas venting systems generating such resistance.
