Description
Technical field
The present invention relates to Digesting stove, particularly have the Digesting stove of heat storage capacity.
Background technology
In the prior art, Digesting stove can be divided into two types, and a kind of is direct-heating type, and a kind of is indirect heating type.
The Digesting stove of direct-heating type directly heats water receptacle, by heating surface the thermal source heat is directly passed to water, and the shortcoming of this Digesting stove is:
1. heating surface is apart from the near position of thermal source, and the temperature height is easily formed thick dirt layer, and dirt layer heat-transfer capability is very poor, and overslaugh is conducted heat.Easily food is burnt, body of heater is short service life.
2. do not have heat accumulation function, put out stove after, water temperature descends soon, needing need the time longer when coolant-temperature gage being raise again, and is unfavorable for operation.
The Digesting stove of indirect heating type places medium with digester, by to the medium heating, by medium the heat transmission is fed water again.This heating furnace is heated evenly digester, is difficult for burning the food in the pot, and this heating furnace has heat accumulation function simultaneously, and after stopping working, medium still can pass to digester with heat, continues cooking.
Present indirect heating type Digesting stove mostly is electrothermal, and adopts oil as medium usually.
With gaseous fuel or liquid fuel is that fuel and the indirect heating type Digesting stove that adopts solid dielectric remain developmental research.
Summary of the invention
The objective of the invention is to design a kind of Digesting stove with strong heat accumulation function, this regenerative furnace is made fuel with gas or liquid, solves general Digesting stove and easily food is burnt problem low with the thermal efficiency, that converter life is short.
Purpose of the present invention can realize by following technical solution:
A kind of phase transformation accumulation of heat Digesting stove, it has a body of heater, the below is the combustion chamber in the body of heater, the top is a flue, and body of heater is provided with stove outer covering outward, leaves the convection current space between this stove outer covering and the body of heater, have outlet flue and connect chimney at stove outer covering, stove outer covering is communicated with convection current space and chimney between the body of heater, and the body of heater place of combustion chamber correspondence is provided with the combustor mouth, it is characterized in that:
The built-in digester of flue leaves the medium space and is provided with some convection current smoke pipes between flue and digester, these convection current smoke pipes are communicated with the convection current space in the combustion chamber and the body of heater outside; Combustion product gases is formed as lower channel: the convection current space → chimney between combustion chamber → convection current smoke pipe → stove outer covering and the body of heater;
The solid heat storage medium is filled in medium space between flue and digester, and described solid heat storage medium is by KNO
3, NaNO
3, NaNO
2The mixture that proportions and form according to designing requirement.
The digester bottom is provided with discharge outlet.
Further design is that body of heater adopts the overhead type design, promptly also leaves the convection current space at the bottom of bottom of furnace body and the stove outer covering, and built on stilts bottom of furnace body (being the bottom, combustion chamber) is provided with refractory insulating layer.
Further design is that stove outer covering increases heat-insulation layer and lagging casing outward.
Auxiliary equipment has the automatic temperature-controlled burner of a cover, and it comprises fuel supply system, combustor, combustor controller, temperature measurer, during use temperature measurer is inserted in the heat storage medium.
During use, in digester, fill water, on combustion control instrument, set the control parameter, start combustor, combustor igniting is the combustion chamber heating, and flue gas is by the convection current space → chimney between convection current smoke pipe → stove outer covering and the body of heater → enter atmosphere, and flue gas heats the convection current smoke pipe.
Combustion chamber and convection current smoke pipe are with the heat storage medium heating in medium space, and the heat absorption of solid heat storage medium is melted and become liquid, by heat storage medium digester is heated heat transferred water and food again.When heat storage medium reached uniform temperature, combustion control instrument was closed combustor automatically, and is flame-out, and at this moment heat storage medium continues digester is passed in the heat release of self savings, makes the food in the pot continue to keep the boiling state.
Because heat storage medium takes place to become liquid by solid in the thermal regenerator process, not only when it discharges heat but also by liquid, become solid, phase transition process like this will absorb/emit a large amount of heats, so heat storage capacity of the present invention is very big.
Be compared with the prior art, the present invention has following outstanding feature and progress:
1. the dual Proper Design that has stove outer covering, good heat insulating.
2. having the long time when flow in the convection current space of flue gas between convection current smoke pipe and stove outer covering and body of heater passes to heat storage medium with heat, makes full use of the combustion heat.
3. solid heat storage medium phase-transition heat-storage has bigger heat storage capacity, after the burner burn-out, continues in the digester to keep the time of boiling state longer.
4. the solid heat storage medium adopts the mixture of several salt, and melting temperature can be regulated by designing requirement, can be according to different temperature retention time needs collocation heat storage mediums to reach best result of use.
5. thermal efficiency height is energy-conservation.
Example with accompanying drawing is further described operation principle of the present invention below:
