Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] Such as figure 1 As shown, the combined heat and power system based on reforming hydrogen production device and fuel cell includes: reforming hydrogen production device 1 and fuel cell stack 2, electric energy converter 3, catalytic heater 4, and carbon catcher 5 with compressor And heat supply heat exchanger 6.

[0022] The reforming hydrogen production unit 1 is a device for converting hydrogen-containing compounds into hydrogen-rich reformed gas. The raw materials for reforming hydrogen production can be hydrocarbons such as natural gas, gasoline, diesel, or alcohols such as methanol and alcohol. Due to the incomplete combustion of raw materials, the hydrogen-enriched reformed gas output from the hydrogen output end of the reforming hydrogen production unit 1 also contains a certain amount of CO.

[0023] The fuel cell st...

Abstract

The invention discloses a combined heat and power system based on a reforming hydrogen production device and fuel cells. The system comprises the reforming hydrogen production device and the fuel cellstack; a reformed gas is conveyed to a heat supply heat exchanger; the heat supply heat exchanger provides heat for the outside; the electric energy of the fuel cell stack is outputted through an electric energy converter; a reforming electric heater and a reforming heat exchanger are arranged in the reforming hydrogen production device; the reforming electric heater is connected with the electric energy converter; electric power required for starting the reforming hydrogen production device and the fuel cell stack is provided by an external electric power source; the reforming electric heater provides heat energy for the hydrogen production of the reforming hydrogen production device; and tail gas outputted by the fuel cell stack is conveyed into a catalytic heater or conveyed into a carbon catcher provided with a compressor. The system of the invention has the advantages of high power generation efficiency, high energy utilization rate and low emission of nitrogen oxide and carbon oxide.

Description

technical field [0001] The invention relates to the technical field of cogeneration systems of heat and power. Background technique [0002] The combined heat and power system can well serve life and production, and meet the needs of lighting, equipment electricity, heating, and hot water in life and production. Traditional cogeneration systems include distributed cogeneration systems based on gas internal combustion engines, distributed cogeneration systems based on gas external combustion engines, distributed cogeneration systems based on micro gas turbines, and so on. However, the defects of the current cogeneration system are: low power generation efficiency, carbon dioxide and harmful substances such as CO and NO X Emissions are high. [0003] The reforming hydrogen production unit converts hydrogen-containing compounds into hydrogen-containing reformed gas. The raw materials for reforming hydrogen production can be natural gas, gasoline, diesel and other hydrocarbon...
