  • The combustion unit 14 includes the waste heat recovery and steam-dump module 140 and the discharge module 141. The waste heat recovery and steam-dump module 140 passes through the gas remixing zone 18 through a pipeline and is coupled to the heat source 13.
  • The air supply unit 15 is coupled to the gas remixing zone 18 through a pipeline. The air supply unit 15 can be an air compressor.
  • The first gas detecting unit 16 is arranged in the gasification unit 12; the second gas detecting unit 17 is arranged in the gas remixing zone 18;
  • With reference to FIG. 2, the present invention is a high efficiency combustion control method, including the following steps:
  • step S1, gasifying the liquid fuel. The air compression unit 19 pressurizes the air and sends the air to the air drying unit 18. The air drying unit 15 dries the air, and the dried air is sent to the air storage unit 11. The air storage unit 11 stores this air.
  • The air storage unit 11 sends the stored air to the gasification unit 12. The energy storage unit 10 sends the stored liquid fuel to the gasification unit 12. The liquid fuel and the air are mixed in the gasification unit 12 to form the first gaseous fuel.
  • step S2, detecting the gas concentration of the first gaseous fuel. The first gas detecting unit 16 detects the first gas concentration of the specific gas in the first gaseous fuel. The specific gas can be oxygen, hydrogen, hydrocarbons or inert gas.
  • step S3, providing the air to the first gaseous fuel. The gasification unit 12 provides the first gaseous fuel to the gas remixing zone 18. The air supply unit 15 provides air to the first gaseous fuel according to the first gas concentration. The first gaseous fuel is mixed with the air to form a second gaseous fuel.
  • step S4, detecting the gas concentration of the second gaseous fuel. The second gas detecting unit 17 detects the second gas concentration of the specific gas in the second gaseous fuel. If the second gas concentration is lower than or beyond the setting range, the air supply unit 15 stops the air supply or adjusts the supply flow rate to the first gaseous fuel.
  • step S5, providing the second gaseous fuel to the combustion unit. The second gaseous fuel in the gas remixing zone 18 enters the combustion unit 13 for combustion.
  • In summary, when the air of the air storage unit 11 enters the gasification unit 12, the pneumatic control valve 110 controls whether the air can flow into the gasification unit 12 or controls the flow rate of air into the gasification unit 12; the manual check valve 111 prevents the air or the first gaseous fuel of the gasification unit 12 from flowing back to the air storage unit 11; the pressure gauge 112 detects the pressure of the air flowing into the gasification unit 12.
  • When the liquid fuel enters the gasification unit 12 from the energy storage unit 10, the pump 100 pressurizes the liquid fuel to gasify.
  • When the first gaseous fuel enters the gas remixing zone 18, the pneumatic control valve 110 controls whether air can flow into the gas remixing zone 18 or the flow rate of air flowing into the gasification unit 12; the manual check valve 111 prevents the air or the first gaseous fuel of the gas remixing zone 18 from flowing back to the air storage unit 11; the pressure gauge 112 detects the pressure of the air flowing into the remix zone 18.
  • After the second gaseous fuel is combusted in the combustion unit 14, the second gaseous fuel after combusting generates exhaust gas and steam. The exhaust gas is discharged to the outside of the combustion unit 14 by the discharge module 141. The steam is directed to the heat source 13 by the waste heat recovery and steam-dump module 140 to heat the first gaseous fuel in the gasification unit 12 and the second gaseous fuel in the gas remixing zone 18.
  • In the present embodiment, the above mentioned specific gas can be oxygen, and the first gas concentration and the second gas concentration are the oxygen concentrations in the first gaseous fuel or the second gaseous fuel.
  • As described above, the change of the first gas concentration or the second gas concentration affects the gasification rate, when the gasification rate increases, the fuel heating value also increases.
  • The following table shows an example where hexane is used:
  •
    Gasification unit 1.4 1.4 1.6
    pressure (kg/cm2)
    Combustion efficiency index 0.68 ± 0.17 0.5 ± 0.09 0.92 ± 0.15
    Combustion average 1.27 1.25 1.32
    consumption (m3/min)
    Average air-fuel ratio (m3/m3) 5.06 ± 0.71 4.2 ± 0.19 7.5 ± 0.5
    Fuel calorific value (kcal/m3) 7647 8912 5452
    Gas fuel density (kg/m3) 1.7 1.77 1.59
    Fuel gasification rate 0.209 0.240 0.155
    (m3/min)
  • As can be seen from the above table, when the fuel gasification rate increases, the fuel calorific value also increases. The present invention uses the first gas detecting unit 16 and the second gas detecting unit 17 to detect the concentration of the specific gas of the first gaseous fuel or the second gaseous fuel respectively. And air is supplied to the liquid fuel or the first gaseous fuel according to the gas concentration, so that the gasification rate is changed, and the calorific value is changed accordingly to obtain the optimal calorific value and the optimal combustion efficiency.
  • The above description is merely illustrative and not restrictive of the invention, and it can be understood by those of ordinary skill in the art that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the claims, which is still within the protection scope of the invention.
