Problems solved by technology

[0004] However, the gasification process of the current alcohol gasification combustion fireplace is relatively simple. The fuel tank directly supplies alcohol fuel to the gasification chamber, and maintains the alcohol in the gasification chamber within a liquid level range, and then directly heats and gasifies.
In this heating method, it is necessary to arrange relevant detection and control elements in the vaporization chamber to maintain the alcohol fuel within a liquid level range, and the vaporization of alcohol fuel in the vaporization chamber needs to be heated above the vaporization temperature of alcohol, and the temperature is relatively high , the relevant detection and control components are not suitable for working in high temperature environment
In addition, not only gasification is required in the gasification chamber, but also related detection and control components need to be arranged, which takes up a lot of space, the inner cavity is large, and can accommodate a lot of alcohol fuel. Moreover, the method of controlling gasification is relatively extensive, the heating and gasification are severe, and the power is unstable. As a result, the flame of the fireplace fluctuates up and down, which not only affects the heating effect, but also reduces the overall viewing effect of the flame, and even vaporizes and boils to produce bubbles overflowing the flame outlet, and the flame exceeds the safe height abnormally, threatening the personal safety of users

Embodiment 1

[0071] Such as Figure 1-7 As shown, a gasification alcohol fireplace includes a shell 1, a burner 2, a gasification chamber 3, a balance chamber 4 and a liquid supply device 5. In this embodiment, the burner 2 is strip-shaped, and the burner 2 It is directly communicated with the gasification chamber 3 through the steam outlet 31, and there are one or more steam outlets 31, and the body of the burner 2 is set higher than the gasification chamber 3 and the steam outlet 31, and the burner 2 is also provided with a flame ejection port 21 , the flame ejection port 21 is multiple and arranged at intervals along the length direction of the burner 2, the gasification chamber 3 is provided with a fuel addition port A 32, the balance chamber 4 is provided with a fuel addition port B 41 and a fuel output port A 42, and the fuel output The port A 42 is connected to the fuel addition port A32 through a pipeline, and a solenoid valve 6 is also arranged on the pipeline between the fuel out...

Embodiment 2

[0079] Such as Figure 8-10 As shown, a gasification alcohol fireplace, compared with Embodiment 1, differs in that: the burner 2 is long and is arranged on the upper part of the gasification chamber 3, and the burner 2 is connected with the gasification chamber 3 through a certain pipeline. The connected pipeline is used as the steam outlet 31, so that the burner 2 does not directly contact the gasification chamber 3. During operation, the temperature generated by the combustion of the burner 2 is not easily transmitted to the gasification chamber 3, thus not affecting the gasification chamber 3 gasification temperature.

[0080] In addition, the ignition device 22 and the flame detection device 23 are respectively arranged at both ends of the burner 2, and are on the same axis as the flame outlet 21, so that it can better ensure and detect all the flame outlets 21 on the entire burner 2 All can emit alcohol vapor and be ignited.

Embodiment 3

[0082] Such as Figures 11 to 13 As shown, a gasified alcohol fireplace, compared with Embodiment 1, differs in that: the burner 2 is set as a curved multi-segment broken line, and the apertures of the flame ejection ports 21 on the burner 2 are set to different sizes, This can better make the flame produced by combustion more tortuous, patchwork, and form a more vigorous effect of the local flame, and the ignition device 22 and the flame detection device 23 are respectively located at the two ends of the burner 2, and are in the same position as the flame ejection port 21. On the same axis, it can be better ensured and detected that alcohol vapor can be ejected and ignited from the flame ejection ports 21 on the entire burner 2 .

Abstract

The invention discloses a stable flame combustion method for a gasified alcohol fireplace. The stable flame combustion method comprises the following steps that (1) alcohol fuel is stored in a liquidstorage area of the gasified alcohol fireplace; (2) a balance area of which the two ends respectively communicate with the liquid storage area and a gasification area and the liquid level is synchronously changed with that of the gasification area, and the alcohol fuel is conveyed from the liquid storage area to the balance area at a stable rate; (3) the liquid level of the balance area is detected in real time to be always at the set working liquid level, when the liquid level of the balance area is higher than the highest working liquid level, the gasification rate of the gasification area is increased, and when the liquid level of the balance area is lower than the lowest working liquid level, the gasification rate of the gasification area is decreased; and (4) alcohol vapor gasified inthe gasification area is guided into a combustion area, and ignited for combustion. Due to the fact that the alcohol fuel is conveyed to the balance area at the stable average speed, the overall alcohol gasification speed of the gasified alcohol fireplace is controlled to be in a relatively stable state, and flames are made to be in a stable state.

Description

technical field [0001] The invention relates to the technical field of alcohol fireplaces, in particular to a method for stable combustion of gasified alcohol fireplace flames. Background technique [0002] Traditional fireplaces mostly use solid fuel for heating. Due to the large storage volume of solid fuel itself, the traditional fireplace occupies a large area, and has low combustion efficiency and poor energy-saving effect. There are also some gas fireplaces that use gas fuel as energy. However, since gas fireplaces usually need to be connected to pipes and special exhaust chimneys need to be installed, the requirements for the house structure are complicated. For example, there is no special reserved structure for installing gas fireplaces during house decoration , it is generally difficult to remodel in the later stage. [0003] With the continuous development of science and technology, alcohol fuel has become a low-pollution, renewable and clean energy. It is lighte...
