The invention discloses a low-volatile briquette coal environment-friendly and energy-saving furnace. A vibration fire grate, an induced air device, a front furnace wall, a rear furnace wall, a primary air heater, a tail flue, a heat exchange water tank and the like are included. The low-volatile briquette coal environment-friendly and energy-saving furnace has the functions that a forward combustion furnace hearth structure is improved, furnace inner gas disturbance is enhanced, black smoke emission is reduced, a smoke and ash waste heat recycling device is additionally arranged, primary airis preheated, the low-volatile fuel combustion capability is enhanced, and clean and efficient gradient utilization of briquette coal is promoted. In the low-volatile briquette coal environment-friendly and energy-saving furnace, the hearth structure is novel; compared with a traditional forward combustion furnace, the furnace temperature can be increased, the furnace inner gas disturbance is enhanced, the briquette coal combustion effect is enhanced, and the briquette coal burn-off rate is increased; a self-heating secondary air system and a waste heat recycling device are introduced, the combustion efficiency of the furnace is improved, a frequency-adjustable vibration fire grate and a wind-frequency-changeable air supply device are applied, the fire power adjusting capability of the furnace is improved, the furnace is integrally high in adaptability to multiple fuels, and the characteristics of economy and practicability are achieved.

The invention relates to the technical field of household gas stoves, in particular to a three-ring fire burner and a gas stove, including a gas distribution seat, and the top of the gas distribution seat is sequentially provided with an outer ring fire cover and an inner ring fire cover. There are several fire holes on the inner side of the fire cover, and fire grooves are arranged between the fire holes. The gas outlet direction of the fire holes and fire grooves points to the central area of ​​the burner. Injection tube, in the present invention, by setting the fire hole and the fire groove pointing to the central area of ​​the burner, heat can be collected and burned, the heating efficiency can be improved, and the heat loss can be reduced. By setting the second fire hole and the third fire hole, it can Increase the area of ​​the fire hole. By setting the partition, the structure of the inner ring fire cover can be made more compact, which can reduce the volume of the top of the burner, increase the heat exchange time and heat exchange area between the bottom of the pot and the flame, and improve the efficiency of gas consumption. The thermal efficiency of the stove is improved, and the cost of the burner is reduced.

The invention relates to the technical field of barbecuing equipment, in particular to a portable barbecuing stove. The portable barbecuing stove is mainly characterized by comprising a stove core, a stove wall, a support rod and a supporting base, wherein the stove core is a polygonal tube or a circular tube; a polygonal or circular opening is formed in the upper end of the stove wall; the stove wall encircles the stove core, and is fixedly connected with the stove core to form a container which has an upward opening and is used for containing barbecuing fuel; the support rod is inserted into the stove core, and can slide relative to the stove core; the relative positions of the support rod and the stove core are fixed through a tightening mechanism; the supporting base is arranged on the support rod, and is used for supporting the support rod. The portable barbecuing stove can be operated by multiple people at the same time, and is convenient to carry.

The invention belongs to the field of cookers, and specifically discloses a gas cooker, which includes a burner, an electrically controlled gas valve, a temperature sensor, a controller and a cooking program built in the controller. The air inlet of the electric control gas valve is communicated with the gas delivery pipe, and the air outlet is respectively communicated with the air inlet of the burner. The temperature sensor and the gas stove assembly are used to detect the temperature of the pot. Cooking programs are configured with time-related setpoints for pot temperature and time. The gas stove is suitable for automatically cooking soup, cooking rice, cooking porridge and pancakes. When cooking food, the controller obtains the cooking program corresponding to the food being cooked. During the cooking process, the controller controls the electric gas valve to adjust the firepower of the burner according to the set value and measured value of the pot temperature in the cooking program. , so that the measured value of the pot temperature reaches the set value until the cooking program is executed and the cooking is completed. During the entire cooking process, the gas stove automatically cooks the ingredients without the user's participation, and can also cook rice with crusts.
