Principle of the present invention be with by the mixed-burned gas liquefaction after the pressurization of described high-pressure service pump with the form of liquid or with the form of threshold state or with the form of ultrahigh pressure gas import high compression engine as described in (as spraying) as described in the firing chamber (in the firing chamber, in the cylinder or in the housing of gas turbine), described mixed-burned gas liquefaction is heated increases the molal quantity of the working medium that participates in acting, thereby increase pressure, improve the acting ability of described high compression engine, then the pressurized gas after the acting of will the expanding acting of further expanding in described low pressure acting mechanism improves the efficient of whole thermal power system.Among the present invention, the importing of described mixed-burned gas liquefaction can make the drop in temperature in the described firing chamber, and thermal capacity increases, and therefore temperature that can the decrease burning can evade the generation of nitrogen oxide.Moreover, because the importing of mixed-burned gas liquefaction can form violent turbulence in the firing chamber, increase fuel mixes with gas, improves combustion efficiency, reduces the discharging of carbon monoxide and solid particulate matter.Although the importing of described mixed-burned gas liquefaction can reduce the temperature in the firing chamber, because the increase of gas phase molal quantity, pressure is not reduced or improve or be improved largely, therefore, although its acting ability of drop in temperature and efficient all can improve.
In order to further specify principle of the present invention, now utilize Figure 18 to be described as follows:
The highest energy state of the gas working medium in the traditional combustion engine cylinder (be the gas working medium state of combustion explosion when just being over, this moment, the temperature and pressure of gas working medium all was the high state that is in the whole circulation) is comprised of two processes: first process be piston to gas carry out adiabatic compression (being actually near adiabatic compresses) with the temperature and pressure of gas according to
(wherein,
Constant) relation carry out supercharging and heat (seeing the curve shown in the O-A among Figure 18); Second process be in gas, spray into heat that fuel produces by the combustion chemistry reaction be close to wait under the state that holds heating with the temperature and pressure of gas according to
(wherein,
Constant) relation heat supercharging (seeing the straight line shown in the A-B among Figure 18).Make working medium be in acting by these two process actings in conjunction and be about to initial state, expansion stroke carries out (seeing the curve shown in the B-C among Figure 18) according to adiabatic expansion (being actually near adiabatic expands), in this adiabatic expansion, in external output work, working medium according to
(wherein,
Constant) concern the step-down cooling until expansion stroke is over (some C shown in state).In other words, reach working medium highest energy state and realize by two various process, and the state when being reached expansion stroke and be over by working medium highest energy state is realized by an adiabatic expansion.Comprised a process that the combustion chemistry exothermic heat of reaction heats up owing to reach in the process of the high state of energy, the temperature and pressure relation of this process is
Be not difficult to find out under the working medium highest energy state and (see the state shown in the some B among Figure 18), temperature is in " surplus " state, and (so-called " surplus " temperature refers to that relation according to adiabatic expansion is in order to reach a certain terminal state, be higher than in theory needed temperature in the true temperature that plays working medium under the dotted state), the temperature of " surplus " causes the curve of inflation process to be in the high temperature position (moving right in Figure 18, Figure 18 is that the longitudinal axis is that the pressure coordinates transverse axis is the pressure and temp graph of a relation of temperature coordinate), when the formation expansion stroke is over, temperature is quite high state (state shown in the some C on the curve shown in curve B-C among Figure 18) still, be not difficult to find out by the state shown in Figure 18 mid point C
(be the Temperature of Working of expansion stroke when being over, the temperature of low-temperature heat source namely) still be in higher state, that is to say still has suitable heat in working medium and does not become merit, and this part heat all is disposed to environment in vain, therefore, efficient can be in low state.In Figure 18, be the curve of conventional engines compression stroke by the curve shown in the O-A, that temperature, pressure in the conventional engines combustion explosion changes straight line by the straight line shown in the A-B, if we are compressed to the air in the atmosphere and import mixed-burned gas liquefaction in the backward cylinder of A point (no matter mixed-burned gas liquefaction is in liquid, threshold state or high pressure low temperature gaseous state), because the pressure of mixed-burned gas liquefaction can be in and be higher than the pressure that A is ordered far away, and its temperature can not be higher than A point temperature, at this moment the state point in the cylinder will move to the upper left side that A is ordered, for example reach the G point, pressure and temp relation when taking fire indoor generation combustion chemistry reaction from the G point reaches the J point by line segment shown in the G-J, begin the expansion acting from the J point and reach a JJ, be not difficult to find out, the temperature of point JJ will be well below the temperature of a C, therefore, the efficient of J-JJ process will significantly be higher than the B-C process.Curve among Figure 18 shown in the O-D is the process that is filled with described oxygen-containing gas liquefied substance in described burst emission engine, straight line shown in the D-E is the straight line that the pressure and temp in the combustion explosion process changes, curve shown in the E-F is the curve that begins to carry out the adiabatic expansion acting from the state shown in the E, be not difficult to find out, its
The value decrease.As calculated as can be known, some E significantly is higher than a B to the efficient of the inflation process of putting C to the efficient of the inflation process of putting F.As shown in figure 18, among the present invention, no matter be the scheme that is provided with internal-combustion engine, still be provided with the scheme of burst emission engine, it is upper or be in curve O-A-H left to make the pressure and temp state point of the working medium after the burning be in curve O-A-H, the Temperature of Working after the acting of then expanding can reach the state that equals the temperature that O orders or be lower than the temperature that O orders, and the efficient of system will be increased substantially.
