Ningbo cassette gas tank is available in kitchen ware market, hotel supplies store, hardware operation department and outdoor supplies store. Because the cassette stove is also called portable butane gas stove, it refers to the non-fixed cooking kitchenware with butane gas as the main fuel and liquefied gas as the fuel, which is directly heated by fire, and is mostly used for family outdoor leisure and hotel supplies. Therefore, Ningbo cassette furnace gas tanks are sold in kitchen ware market, hotel supplies firm, hardware operation department and outdoor supplies store. Barrel furnaces are mostly ignited by piezoelectric ceramics, and the biggest advantage is that they do not need batteries. However, the success rate of ignition is related to the environmental humidity, and it is not easy to ignite when the humidity is high. In addition, it is necessary to hold down the switch to ignite, which is not as fast as electronic pulse ignition. Of course, the success rate and firing times of piezoelectric ceramics also depend on the quality of the magnetic needle. A good magnetic needle can be clicked for tens of thousands of times or more, and a general or poor quality magnetic needle may only be clicked for thousands of times.
