Description

An energy-saving fuel stove

technical field

The utility model relates to the technical field of fuel oil stoves, in particular to an energy-saving fuel oil stove that can fully burn fuel oil and achieve energy-saving effects.

Background technique

At present, in various hotels, restaurants, colleges, factories and other places, due to the large number of people dining in them, the large kitchens equipped in these large places all use oil-fired cooking stoves. Insufficient combustion, serious pollution and other problems, and because of its incomplete combustion, it also causes a substantial increase in fuel consumption. Due to the high ignition point of fuel oil, many oil stoves use ignition rods to ignite at present, which is inconvenient to operate.

Utility model content

The purpose of the utility model is to provide an energy-saving fuel oil stove that can fully burn fuel oil and achieve energy-saving effects in view of the shortcomings of the prior art. It has the advantages of low consumption, environmental protection, simple structure, and easy operation.

In order to achieve the above object, the utility model adopts the following technical scheme: according to the utility model, the energy-saving fuel oil stove includes a furnace body, a primary oil delivery pipe is connected to the middle and lower part of the inner wall of the furnace body, and a secondary oil delivery pipe is connected to the inner bottom; the furnace There is a fire cover fixed in the body, the fire cover is hollow, and there are many air holes on the wall of the device.

Preferably, an air intake passage is formed between the inner wall and the outer wall of the furnace body, and a plurality of air holes are opened on the inner wall, and the air flow enters the furnace body through the air holes on the inner wall and is mixed and burned in proportion.

Preferably, the part of the bottom of the furnace body in contact with the fire cover is provided with a plurality of air intake holes, through which the airflow can directly enter the fire cover for combustion.

Preferably, an electronic igniter is fixed at the bottom of the furnace body, and the electronic igniter is connected to the gas pipe.

The primary oil delivery pipe is arranged at the middle and lower part of the inner wall of the furnace. When the fuel oil enters the combustion chamber through the primary oil delivery pipe and burns, the secondary oil delivery pipe is opened. The secondary fuel delivery pipe is installed at the bottom of the furnace body. When the diesel oil enters the combustion chamber through the secondary fuel delivery pipe, the fuel oil that enters the combustion chamber through the primary fuel delivery pipe has already caught fire. At this time, the fuel oil is rapidly cracked and evaporated by high temperature. Combined with the airflow entering the combustion through the air holes on the inner wall, the combustion is mixed in proportion, and the combustion is complete and pollution-free.

The utility model fully evaporates, cracks, atomizes, and gasifies the fuel in the fire cover through two fuel injections, and then mixes an appropriate proportion of air to generate strong firepower, and has the advantages of high calorific value, low fuel consumption, energy saving, and environmental protection. Etc.

Description of drawings

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model

Detailed ways

Referring to Fig. 1, the utility model includes a furnace body 1, and the furnace body 1 adopts high temperature resistant steel material to be cast. The furnace body 1 is "U"-shaped, and its interior is connected with a primary oil delivery pipe 3 and a secondary oil delivery pipe 8. Fuel (which can be diesel) enters the furnace body 1 through the primary oil delivery pipe 3 and the secondary oil delivery pipe 8. Combustion is carried out in the combustion chamber 7.

An air intake channel 5 is formed between the inner wall and the outer wall of the furnace body 1, and there are a plurality of air holes on the inner wall. Stomach enters in the combustion chamber 7 and burns. A fire cover 4 is fixed in the body of heater 1, and the fire cover 4 is directly fixed on the inner bottom of the body of heater 1. The fire cover 4 is hollow and has a plurality of air holes on the wall. The part of the bottom of the furnace body 1 in contact with the fire cover 4 is provided with a plurality of air holes. The primary oil delivery pipe 3 is arranged at the middle and lower part of the inner wall of the furnace body 1 , and the secondary oil delivery pipe is arranged at the inner bottom of the furnace body 1 . For making ignition convenient, the inner bottom of body of heater 1 of the present utility model is fixedly installed electronic igniter 2, and electronic igniter 2 is conventional device, and electronic igniter 2 is connected with gas pipe 6.

The working principle of the utility model is as follows:

Turn on the electronic igniter 2 and ignite the kindling; when the fuel with the rated flow rate enters the combustion chamber 7 through the primary fuel delivery pipe 3, at the position A in the fire cover 4, the fuel is heated to the boiling point and evaporates, and the fuel starts to burn as the temperature increases. Cracking and decomposition, when the fuel oil starts to produce an open flame, the electronic igniter 2 and the gas pipe 6 can be closed. At this time, the combustion of the fuel is not sufficient. At this time, it is necessary to open the secondary oil delivery pipe 8, because the fuel oil entering the combustion chamber through the primary oil delivery pipe 3 has been ignited and burned, and the temperature of the combustion chamber has increased. , evaporation, so that the combustion of fuel is more sufficient and more stable; at the same time, the secondary fuel delivery can more effectively control the size of the flame. When the fire is slow, the flame will not appear to be extinguished; , due to the instantaneous cracking and evaporation of fuel oil under the action of high temperature, the flame temperature increases sharply and more heat energy is generated. In addition, because the combustion is completed by sending oil twice, and the fuel consumption into the combustion chamber is small, the oxygen required for fuel combustion is also reduced. We will close the exhaust hole, and the flame will not will be extinguished, and the energy released by the fuel will be used by us more.

As the temperature of the combustion chamber increases, the cracking speed of the fuel increases. At the position B of the fire cover 4, the fuel is atomized into particles. At this time, the gasification speed of the fuel is accelerated, and it is fully mixed with the air sent into the intake pipe 5; At position C of the fire cover 4, the fuel particles have been converted into gas, which are mixed with air in a certain proportion and fully burned. The flame is translucent, forming a very high temperature heat flow, and the temperature can reach 650-1100 degrees.

In the utility model, 4 is fixedly installed in the furnace body 1, and the primary fuel delivery pipe 3 and the secondary fuel delivery pipe 8 are arranged at the middle and lower part of the inner wall, so that the fuel oil can be more fully cracked and finally gasified, thereby making the fuel oil Combustion is more complete, and then achieve high calorific value, less fuel consumption, energy saving, environmental protection, etc.

Of course, the above-described embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model. Equivalent changes or modifications shall be included in the patent scope of the utility model.
