Secondly, the combustion of the fireplace can quickly reach the required temperature while saving fuel; it can completely discharge the exhausted gas to the outside and minimize the heat loss; it can not only intuitively burn the inside of the fireplace. It is also possible to remotely operate automatic control and operate safely and reliably. These are all issues that must be considered in assessing the pros and cons of gas fireplaces.
  • the conventional manual control ignition has been used, and the size of the flame is manually adjusted, and the working condition in the fireplace cannot be visually observed.
  • the fireplace When the fireplace is ignited and the flame size is adjusted, it must even be operated underground by hand, that is, it takes time and effort, and it is easy to damage the control components. Moreover, it is operated by personal feeling, and it is difficult to control the combustion at an optimal state. It is even more difficult to accurately control the indoor temperature, and there is no clear judgment on the fault.
  • Some fireplaces are ignited by a long flame, as long as the fireplace is turned on and the fire is on, it must be ignited until the fireplace stops working. This structure is prone to failure due to carbon deposition, which is neither safe nor wastes gas.
  • such a gas fireplace with an in-line exhaust system has the following drawbacks: First, in order to increase the exhausting force, the diameter of the exhaust pipe must be large, and the radius of the pipe bend is large, and must be The part of the pipe with a vertical length of 4111 should be used as the wind extraction; the second is because the wind speed of the exhaust pipe is small, it must have a device to prevent backflow of wind.

In the middle, the flame of the long fire is needed from the beginning, so it not only wastes energy (gas), but also the thermocouple of the detecting element is in the flame for a long time and is easily burned. Therefore, the long fire ignition device not only consumes a large amount of energy, but also frequently replaces the thermocouple and is unsafe (due to the presence of a long open flame).
