Abstract

본 발명은 외기의 영향에 의한 송풍량의 변동이 없고, 공기와 연료의 비를 적정하게 유지할 수 있는 연소제어장치를 제공하는 것을 목적으로 하는 것이며, 그 구성은 공기흐름센서(26)에 의하여 검출한 송풍량과 송풍기(12)의 검출회전구로 부터 송풍기(12)의 제어회전수를 보정하기 위한 보정율을 산출하고, 요구열량에 대응하여 산출된 기본회전수를 보정하여 제어회전수를 결정하고, 또 송풍기(12)의 검출회전수를 보정율의 역수로 보정한 회전수로부터 비례밸브(16)로의 통전용전류값을 환산하여 비례밸브(16)를 구동하고, 또한 송풍량의 변동시에 송풍기(12)의 제어회전수만을 변경하여 송풍량을 요구열량에 대응시킴으로써, 이때 비례밸브(16)의 전류값은 변동하지 않기 때문에 버너(11,11a)의 공기와 연료의 비를 유지할 수 있도록 한 것이다.It is an object of the present invention to provide a combustion control device which can maintain an appropriate ratio of air and fuel without fluctuations in the amount of blowing due to the influence of outside air, and its configuration is detected by the air flow sensor 26. A correction rate for correcting the control rotation speed of the blower 12 is calculated from the blower amount and the detection rotation hole of the blower 12, and the control rotation speed is determined by correcting the calculated basic rotation speed corresponding to the required heat amount; The proportional valve 16 is driven by converting the energized current value to the proportional valve 16 from the rotational speed at which the detected rotational speed of the blower 12 is corrected to the inverse of the correction rate. By changing only the control speed of the t), the blowing amount corresponds to the required heat amount, so that the current value of the proportional valve 16 does not change at this time, so that the ratio of air and fuel of the burners 11 and 11a can be maintained.
