In the hearts of many consumers, there is such a misunderstanding: the gas stove with the greater firepower is better. In response to this psychological misunderstanding, some merchants began to publicize their products with high firepower and high efficiency. However, the greater the firepower, the greater the amount of gas consumed per unit time, so the so-called firepower and energy saving arguments are untenable.
After long-term research, gas technology engineers found that the heat flow control of household embedded gas stoves is between 3.5KW and 4.0KW, so that the firepower is large enough, the thermal efficiency is also high, the combustion is fully stable, and the best combustion equilibrium point is achieved.
Therefore, consumers should pay attention to the purchase of gas stoves, the heat flow (firepower) of the product must be greater than 2.91KW (national standard), but should not exceed 4.0KW; combustion sufficient (CO displacement) must be less than 0.05%; flameout protection device The automatic valve closing time should be less than 60 seconds. Those that meet these standards are high quality gas stoves.
H section steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a profile of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries.
