Technical Field
The application relates to the technical field of Stirling generators, in particular to a combined heat and power boiler system with a Stirling generator set.
Background
The Stirling generator is an external combustion engine, and utilizes a heater of the Stirling generator to absorb an external high-temperature heat source, heat an internal working medium and complete the working processes of heating, expanding, cooling and compressing, so that components such as a piston, a connecting rod, a crankshaft and the like work, and finally the generator is driven to work to output electric energy. The Stirling generator only utilizes the heater to exchange external energy to heat working medium gas in the cylinder, and the working medium gas is not combusted in the cylinder like an internal combustion engine, so that high-temperature exhaust is not generated, and secondary pollution to the atmosphere is not generated. In addition, because the interior of the Stirling generator is in closed circulation, no special requirement is required for the form of an external heat source, and the Stirling generator can be widely applied as long as the temperature of the heat source meets certain requirements.
The boiler generally generates high-temperature flue gas by burning fuel, and the high-temperature flue gas exchanges heat with water to generate hot water or steam for production or living use, but in the working process of the boiler, certain electric energy needs to be consumed due to the need of the cooperation of an auxiliary system, and the part of energy consumption is also a factor which has to be considered in the comprehensive cost of boiler operation. Based on the above characteristics of the stirling engine, it has been found that the stirling engine is combined with a boiler, and the electricity generated by the stirling engine is used to power the auxiliary system of the boiler.

the Stirling generator 3 is started and installed on the boiler 2 body and used for absorbing high-temperature flue gas energy in the boiler 2 hearth, so that the generator is driven to generate electricity. After passing through the stirling generator 3, the flue gas in the boiler 2 enters the boiler heat exchange tube to heat water supplied by the boiler water supply system, and finally hot water or steam is generated and supplied to a required place through the steam pipeline 101. The flue gas passes through the boiler 2, then passes through the flue gas outlet 10 to be discharged, and then is discharged to the atmosphere after being treated by tail gas.
The Stirling generator gas supplementing system 4 provides a gas supplementing function for the Stirling generator 3 in the working process; the Stirling generator cooling system 5 provides a cooling function for the Stirling generator 3;
the system realizes the increase of the power generation function in the traditional boiler system, utilizes the characteristics of the external combustion engine of the Stirling generator, absorbs the heat of high-temperature gas in the hearth of the boiler to directly generate power, and produces hot water or steam by the heat which is not absorbed by the Stirling generator through the heat exchange tube of the boiler, thereby realizing the maximization of the comprehensive efficiency of cogeneration.
