Description

An environment-friendly and energy-saving supporting device for burning appliances

Technical field

The utility model relates to an energy-saving and environment-friendly support device on a gas cooker, in particular to an energy-saving and environment-friendly support furnace frame on a gas cooker.

Background technique

Commonly used gas stoves are generally divided into two types: embedded and desktop, and the combustion methods are generally divided into two types: atmospheric combustion and porous infrared radiation combustion. Regardless of whether it is an embedded or desktop gas stove, whether it is atmospheric combustion or infrared radiation combustion, there are heat loss problems to varying degrees. Especially the open combustion between the gas stove and the cooker makes the heat loss phenomenon very obvious. This is because the heat released by the combustion of gas heats the cooker and releases a large amount of heat to the outside in the form of heat convection, heat conduction, and heat radiation around the cooker, especially when the flame is disturbed by the air. The loss of heat energy is more serious. When burning with the center ring "little flame", a slight breeze can blow out the flame. Due to the relatively serious convection heat dissipation in the open combustion, the residence time of the flue gas in the combustion reaction zone is short, the temperature of the combustion zone is reduced, the CO content in the flue gas produced by incomplete combustion increases, and the efficiency decreases.

At present, the national standard GB16410-2007 stipulates that the thermal efficiency of desktop stoves is ≥55%, the efficiency of embedded stoves is ≥50%, and the CO concentration in dry flue gas is ≤500ppm. However, as the service life increases, the thermal efficiency of cooking utensils is affected by various factors, and the thermal efficiency of the cooker also decreases, and the reduction of thermal efficiency will also lead to an increase in the emission of incomplete combustion gases such as CO, which not only wastes energy, but also pollutes the environment and affects users. health.

Contents of the invention

In order to overcome the disadvantages of low combustion heat transfer efficiency and high content of CO and NOx in flue gas produced by combustion in existing gas appliances, the utility model provides an energy-saving and environment-friendly supporting furnace frame, which makes the traditional open combustion into a The semi-closed combustion reduces the convection, radiation and conduction heat loss of the heat generated by gas combustion to the outside, and improves the thermal efficiency. After testing, the thermal efficiency of the energy-saving hob can be increased by 10-15% compared with that of the common hob. The semi-closed combustion prolongs the residence time of the flue gas in the combustion reaction area, forms the backflow of the flue gas in the high temperature area, keeps the temperature of the combustion area high, increases the rate of combustion reaction, makes the combustion more complete, and greatly reduces the combustion rate. CO content in flue gas. After testing, the CO content in the flue gas of the gas stove using this energy-saving hob is far lower than the 500ppm index of the national standard. At the same time, due to the use of semi-closed combustion, the gas stove has greater environmental adaptability and can resist the interference of relatively large ambient air flow. When using the central fire "small flame" to burn, it can not only improve the thermal efficiency of combustion, but also prevent the airflow from blowing out the small fire. In this way, when the cooker and the range hood are matched, a high-power range hood can be selected, or the installation height of the range hood can be lowered, so that the kitchen fume can be exhausted outdoors to the maximum extent, which greatly improves the indoor environment of the kitchen.

The technical solution adopted by the utility model to solve the technical problem is: an environmental protection and energy-saving supporting device for burning appliances, including: an energy-saving plate, a heat insulation layer, a shell, a corrugated boss, a pot support block, and a support . Its structural features are: the ring-shaped curved disc body and the shell form a closed "space chamber", and the "space chamber" is filled with materials with high thermal resistance (such as pearlescent sand, etc.) or pumped into a certain degree of vacuum or filled with high thermal conductivity. The "space chamber" restricts the flow of gas, reduces the loss of convection and heat conduction, and radiates the heat released by combustion to the bottom of the pot. The corrugated boss on the disc body can change the flow state of the gas, the pan support block is connected with the disc body to support a pan or a pan with a pointed bottom, and the support is connected with the shell to support the entire disc body. The entire supporting hob rests on the burners of the hob.

The shape of the above-mentioned curved disc can be curved or linear, and can be provided with corrugated bosses and reverse folded edges.

There are at least three pot support blocks, which can be evenly or non-uniformly distributed.

The above-mentioned thermal insulation layer can be filled with high thermal resistance material, or evacuated or filled with gas with low thermal conductivity.

The above-mentioned support can be cylindrical, also can be circular truncated, also can have the saddle shape of radian, can be punched on the support to supplement the secondary air of combustion.

The beneficial effects of the utility model are: the open combustion is changed into a semi-closed combustion, the thermal efficiency of gas combustion is improved, the flue gas stays in the high-temperature combustion reaction zone for a long time, the chemical reaction rate is high, the gas combustion is sufficient, and the gas in the flue gas The C0 content is low. After testing, the thermal efficiency of the energy-saving hob can be increased by 10-15% compared with that of the common hob, and the CO content in the flue gas of the gas stove is far lower than the national standard of 500ppm. The semi-closed structure achieves the purpose of windproof and improves the environmental adaptability of the gas cooker. When the "small flame" of the central fire is burning, the use of this energy-saving and environmentally friendly hob can not only improve the combustion thermal efficiency, but also the flame is not easy to be blown out by the wind. safer. After the stove is extinguished, the energy-saving stove frame radiates the heat stored on components such as the fire distributor and the pan body to the cooker through heat preservation and radiation, so as to further utilize the waste heat. When the cooker is used in conjunction with the range hood, a high-power range hood can be selected or the installation height of the range hood can be lowered to further purify the indoor environment of the kitchen and achieve environmental protection and energy saving effects. The structure is simple and easy to process and manufacture.
