Movable water boiling stove for heating and cooking with double layer heat exchanger

Abstract

The movable heating and cooking water heater with double layer heat exchanger consists of housing, door, double layer heat exchanger, automatic control valve connected in the pipeline, detachable and replaceable stove, etc. The present invention has the advantages including capacity of replacing various kinds of stove, including gas burning stove, coal stove, electric stove, etc., capacity of taking the stove out of the water heater for cooking, raised heat efficiency owing to the double layer heat exchanger, and capability of using all the year round.

Description

technical field [0001] The invention relates to a stove that can be used for heating, cooking and sanitation, and the burning raw materials can be replaced at will. More specifically, the invention relates to a movable double-layer heat exchanger for heating and cooking hot water. furnace. Background technique [0002] At present, the heating furnaces sold in the market, such as Sangpu heating furnaces, all use circulating water jackets around the coal-fired stoves to heat the heating circulating water system. In order to improve thermal efficiency, some also set circulating water around the chimney. set. However, because these methods only utilize heat conduction and heat radiation to absorb heat, and heat convection has not been fully utilized, high-temperature flue gas will quickly go to the outside atmosphere along the chimney, so its thermal efficiency can only reach 30% to 40%, a great waste of energy. Another disadvantage of it is: b...

Problems solved by technology

However, because these methods only utilize heat conduction and heat radiation to absorb heat, and heat convection has not been fully utilized, high-temperature flue gas will quickly go to the outside atmosphere along the chimney, so its thermal efficiency can only reach 30% to 40%, a huge waste of energy

Another disadvantage of it is: because there is no sanitary water pipe design, it can only be used for heating in winter and cannot be used for bathing in summer. The stove has to be idle for more than eight months every year, and it is easy to rust and damage

Another example is the Yandi brand wall-mounted heating furnace, etc. Its heat exchanger for heating the circulating water system is combined with the sanitary water heat exchanger set, and it is single-layer, and its specific surface area is quite large. Small, almost one-tenth of the ordinary heating furnace is not enough. In order to meet the temperature requirements of heating and sanitary water, it is necessary to use a large amount of fire and instant burning method to make the heat exchanger heat up rapidly in a short time. This method It can only let most of its heat energy run away without enough time to absorb, so its energy waste is quite large, and its thermal efficiency only reaches 20% to 30%. When sanitation water is not used, but only for heating circulating water system to raise the temperature, the sanitation water heat exchanger will also heat up, causing partial overheating and boiling and explosion

In addition, the combustion source of this kind of stove is fixed, so the combustion source cannot be changed at will, and it cannot be used for cooking and cooking.
