Abstract

This design is a dual-use electric boiler that minimizes the overall volume of the boiler while properly distributing the heat transfer area and efficiently internalizes the heat generating parts of the oil and electric heat source, maximizing thermal efficiency. It is easy to install and has the advantage of being able to supply more cheaply. It has an oil combustion chamber in the lower part of the boiler water chamber, and the combustion gas turns to the descending air after the rising airflow, so that the residence time in the furnace is increased to secure a lot of heat conduction time and again. The heat efficiency is increased by attaching a fin (wing) to the outside of the combustion chamber along with the structure that increases the thermal efficiency through the flue connected from the bottom of the chamber to the top.The heating water is heated by heat source using electric energy from the electric heater at the upper end of the combustion chamber. And hot water heating coil is built in the upper part It will been configured to supply.

Description

Oil combined electric boiler {AAAAA}

Manufacturing and distributing oil-combined electric boilers that can be economically supplied from manufacturing to real demand while minimizing the structure while maximizing the thermal efficiency.

In general, it is already known that a boiler that combines electricity and oil is basically composed of a heater that generates heat by receiving electric energy from a firebox and a water chamber for oil combustion.

Therefore, the oil-based electric boiler is a research subject to efficiently configure the above structure to increase the thermal efficiency and to reduce the cost.

In other words, since the oil-based electric boiler uses two energy sources, the price is also significantly increased due to its complicated structure and bulkiness. Therefore, it is difficult to install and handle transportation and handling in addition to uneconomical problems such as economic burden on the consumer. do.

In this respect, the oil-combined electric boiler of the prior art disclosed in Korean Utility Model Publication No. 90-6957 has the problems mentioned above.
