Liquid piston heat engine and boiler having the same

Abstract

Disclosed are a liquid piston stirling engine and a boiler having the same. The liquid piston stirling engine comprises a first cylinder, a second cylinder, a heater, a heat regenerator and a cooler, wherein liquid pistons of which the bottoms are in communication with each other are arranged in the first cylinder and the second cylinder; the heater, the heat regenerator, and the cooler are connected together in sequence, the first cylinder is connected with the heater, and the second cylinder is connected with the cooler; and the liquid piston stirling engine also comprises a power output tube, wherein the first end of the power output tube is provided with a power output port, and the power output tube is extended into the first cylinder or connected to the bottom of the first cylinder to output the back-and-forth power outwards through the second end of the power output tube. The liquid piston stirling engine and the boiler using same in the present invention have low costs, less noise, and energy saving and environment protection.

Description

technical field [0001] The invention relates to a heat engine and a boiler, in particular to a liquid piston heat engine and a boiler with the liquid piston heat engine. Background technique [0002] The heat engine is an external combustion closed-cycle reciprocating piston heat engine. Because it was invented by Stirling in Scotland in 1816, it is also called the Stirling engine, also known as the heat engine. The medium substance (usually high-pressure gas) that transfers energy in the heat engine is called working medium, and a certain volume of working medium is filled in one, two, four or more closed cylinders. One end of the cylinder is a hot chamber and the other end is a cold chamber. The working medium is compressed in the low-temperature cold chamber, and then flows into the high-temperature hot chamber to be heated rapidly and expand to do work. The heat brought by the continuous combustion of the fuel in the combustion chamber outside the cylinder or the exter...

Problems solved by technology

[0006] In addition, the boiler is an important living equipment. When it is heating, the circulating water system of the boiler needs power. The traditional circulating water system uses the electric water pump as the power source, but the electric water pump has the disadvantage of loud noise, and there are Vulnerable parts require daily maintenance, which affects the convenience of use

and does not work during a power outage

Boilers are usually powered by coal or natural gas, while water pumps are powered by electricity, which does not make full and reasonable use of energy, and is not effective in energy saving and environmental protection
