Method of detecting a blocking of air supplying and exhausting pipes of combustion facilities

본 발명은 연소기기 급배기 폐쇄 검지 방법에 관한 것으로, 연소 요구가 발생하면 연소 전에 팬을 미리 정한 퍼지(purge) 회전수로 작동한 후 연소기에서 연소하는 혼합가스를 만들기 위해 가스공급밸브를 경유하여 혼합챔버 내부로 공급되는 가스의 공급압력을 상기 가스공급밸브의 가스배출라인 상에서 검출하고, 해당 검출압력을 미리 정한 퍼지압력 혹은 미리 정한 연소압력과 비교한 결과에 따라 정상 연소를 하거나 연소기기의 급배기 폐쇄 여부를 검지하여 실제 급배기 폐쇄가 확인되면 팬을 정지하여 연소기의 연소 작동을 정지하고 에러를 발생하는 연소기기의 팬을 정지하여 연소 작동을 정지하고 에러를 발생한다. 본 발명에 따라 혼합챔버 내부로 공급되는 가스의 공급압력을 가스공급밸브의 가스배출라인 상에서 검출하면 가스 검지 혹은 혼합가스 검지 오류가 없으므로 제품에 대한 클레임을 방지할 수 있고, 종래에 급기되는 공기의 압력을 검지하는 방식에서 연소 시 최대열량부터 최소열량까지 전 영역을 검지하기 위해서 차압을 높게 측정할 수 있도록 고가의 차압센서를 추가 부품으로 사용해야 하는 단점을 해소할 수 있고, 고가의 차압센서보다 상대적으로 더 저렴한 압력센서로 연소기기의 급배기 폐쇄 여부를 검지하여 과열 사고 등의 위험을 초래할 수 있는 불안전 연소를 방지하고 제품의 안전성을 향상시킬 수 있다. The present invention relates to a method for detecting air supply/exhaust closure of a combustion device. When a combustion request occurs, the fan operates at a predetermined purge rotation speed before combustion, and then through a gas supply valve to make a mixed gas that is burned in the combustor. The supply pressure of the gas supplied into the mixing chamber is detected on the gas discharge line of the gas supply valve, and the detection pressure is compared with a predetermined purge pressure or a predetermined combustion pressure to achieve normal combustion or the supply of a combustion device. When the actual supply and exhaust closure is confirmed by detecting whether the exhaust is closed, the fan is stopped to stop the combustion operation of the combustor, and the fan of the combustor generating an error is stopped to stop the combustion operation and generate an error. According to the present invention, when the supply pressure of the gas supplied into the mixing chamber is detected on the gas discharge line of the gas supply valve, there is no gas detection or mixed gas detection error, so claims against the product can be prevented, and In the pressure detection method, it can solve the disadvantage of using an expensive differential pressure sensor as an additional component to measure the ...

A combustion system and a method for adapting the combustion system to utilize a first fuel when the system has been designed for a second fuel. The method and system provide inlets for adding air to lower the quality of the first fuel to the quality of the second fuel or inlets for adding a third fuel of a higher quality than the second fuel to raise the quality of the first fuel to the level of the quality of the second fuel.

Vehicle heater and controls therefor

A heater for a liquid has a combustion chamber, a jacket for the liquid extending about the combustion chamber and a burner head assembly connected to the combustion chamber. The burner head assembly includes a housing having a burner mounted thereon and a hollow interior. A control module and a fan are mounted in the hollow interior, the fan being connected to an electric motor. A compressor and a fuel pump are mounted on the housing and are operatively connected to the electric motor. The control module may include controls for exercising components of the heater prior to combustion, thereby verifying operation of these components. Preferably there is a speed control for the motor, such as a closed loop speed control which regulates motor speed and accordingly output of the heater. Preferably there is a backup system using a lookup table in the event that the closed loop speed control fails. Also preferably there is provision for monitoring flame sensor functionality by providing an indicator light which mirrors operation of the flame sensor. The heater may have a selective soft start for the coolant pump which operates only when required so as to reduce unnecessary chatter on the motor relay. A system is also provided for distinguishing true overcurrent faults from overcurrents arising from voltage changes during starting of the vehicle engine. Reignition algorithms are provided to restart the burner in the event of flame sputters caused, for example, by fuel bubbles, but shut off the heater in the event that the fuel is truly cut off.

Atomic absorption spectroanalytical instrument control system

A sensor responsive to hydroxyl ions is provided to monitor the flame at the burner in an atomic absorption spectroanalysis system. The sensor in the disclosed embodiment includes an S4 photodiode and a filter to provide a sensitivity over the wavelength band of 3000-3900 A. The output of the photodiode is applied via an FET amplifier stage and an emitter follower stage to burner control circuitry. The burner control circuitry initiates flame via a pilot line, and if hydroxyl ions are not sensed within a predetermined time, the system is automatically shut down. After flame is established, an interlock permits switching from air to nitrous oxide and on failure to sense hydroxyl ions, the nitrous oxide, the fuel and then the air are turned off in sequence in response to the output of the sensor.

Method for characteristics adjustment of burners

The method involves varying the power of the burner (1) based on a first power value (P1), an air parameter (Aj), fuel parameter (Fj) and additional parameter (Hj). The change in power changes the air flow and/or fuel flow and/or auxiliary drive in a first direction (Rj) until the exhaust gas parameters change upon occurrence of the next power value (Pi+1). A least one next air parameter (Ai+1) and/or fuel parameter (Fi+1 are determined so that defined exhaust gas parameters can be set.
