Detailed description of the invention
Be example with burnt gas wall hanging furnace below, the invention will be further described.
As shown in Figure 1 and Figure 4, this burnt gas wall hanging furnace forms primarily of controller 1, display screen 2, gas ratio valve 3, outdoor temperature sensor 4 and frequency conversion fan 5.Display screen 2, gas ratio valve 3, outdoor temperature sensor 4 and frequency conversion fan 5 are electrically connected with controller 1 respectively, controller 1 upgrades every unit interval T1 and records outdoor temperature, and according to the change of adjacent twice outdoor temperature, regulate the rotating speed of frequency conversion fan 5, and controller 1 calculates to the PWM value of frequency conversion fan 5 output or the rotating speed of frequency conversion fan 5 gas quantity flowing through gas ratio valve 3 according to it, and by result of calculation display on the display screen 2.
The computational methods of this burnt gas wall hanging furnace amount of consumed gas, carry out according to following steps:
A, burnt gas wall hanging furnace starts burning; Controller 1 upgrades every unit interval T1 and records outdoor temperature.
B, controller 1 judges whether outdoor temperature is positioned at temperature and regulates compensated section; If outdoor temperature regulates in compensated section in temperature, then enter step C; If outdoor temperature does not regulate in compensated section in temperature, then enter step D.
C, controller 1 judges the lifting of outdoor temperature; If outdoor temperature declines, then increase the rotating speed of frequency conversion fan 5; If outdoor temperature raises, then reduce the rotating speed of frequency conversion fan 5.
D, controller 1 calculates to the PWM value of frequency conversion fan 5 output or the rotating speed of frequency conversion fan 5 gas flow flowing through gas ratio valve 3 according to it.
E, the gas flow result that display screen 2 display controller 1 calculates.Gas flow result is the mean value flowing through the gas flow of gas ratio valve 3 in unit time T2.
Temperature in step B regulates compensated section to refer to outdoor temperature section by regulating burning load (power) can reach the system thermal equilibrium of supply and demand, that is, the temperature section of TC1 ~ TC2 as shown in Figure 3.If outdoor temperature is too low, exceed temperature to regulate compensated section and burnt gas wall hanging furnace to be in the highest burning load (power) to run, even if outdoor temperature declines, burnt gas wall hanging furnace still maintains the highest burning load (power) and runs, without the need to regulating set temperature and frequency conversion fan 5 rotating speed; If outdoor temperature is too high, exceed temperature to regulate compensated section and burnt gas wall hanging furnace to be in minimum burning load (power) to run, even if outdoor temperature rises, burnt gas wall hanging furnace still maintains minimum burning load (power) and runs, without the need to regulating set temperature and frequency conversion fan 5 rotating speed.
When outdoor temperature sensor 4 senses that outdoor temperature declines to some extent, and judge to determine that outdoor temperature is in temperature and regulates in compensating basin according to the relation curve of outdoor temperature and set temperature, then need to improve fired heat duty (power) to reach the equilibrium of supply and demand of system thermal.Now, controller 1 carries out automatic adjustment height by the set temperature of burnt gas wall hanging furnace, and the PWM value that continuous adjustment controller 1 exports to frequency conversion fan 5, frequency conversion fan 5 rotating speed is improved constantly, air quantity constantly increases, and gas ratio valve 3 is by the pressure increase of frequency conversion fan 5, and valve body aperture increases gradually, gas flow also increases gradually, and fired heat duty increases thereupon.The rotating speed of controller 1 according to frequency conversion fan 5 and the relation curve of gas flow, as shown in Figure 2, extrapolate in unit interval T2 the gas flow mean value flowing through gas ratio valve 3, by Program transformation, gas flow signal is transported to display screen 2 with Time Controller 1, display screen 2 is transferred to data signal and is shown.As, display screen 2 shows " 2.6 " numeral, then represent that now gas flow is about 2.6m
3/ H, makes user can understand the combustion gas air consumption of burnt gas wall hanging furnace in real time.
When outdoor temperature sensor 4 senses that outdoor temperature raises to some extent, and judge to determine that outdoor temperature is in temperature and regulates in compensating basin according to the relation curve of outdoor temperature and set temperature, then need to reduce burning load (power) to reach the equilibrium of supply and demand of system thermal, its adjustment process is then contrary.Controller 1 is turned down automatically by the set temperature of burnt gas wall hanging furnace, and the PWM value that continuous adjustment controller 1 exports to frequency conversion fan 5, frequency conversion fan 5 rotating speed is constantly reduced, air quantity constantly reduces, gas ratio valve 3 reduces by the pressure of frequency conversion fan 5, valve body aperture reduces gradually, and gas flow also reduces gradually, and fired heat duty reduces thereupon.The rotating speed of controller 1 according to frequency conversion fan 5 and the relation curve of gas flow, as shown in Figure 2, extrapolate in unit interval T2 the gas flow mean value flowing through gas ratio valve 3, by Program transformation, gas flow signal is transported to display screen 2 with Time Controller 1, display screen 2 is transferred to data signal and is shown.As, display screen 2 shows " 2.2 " numeral, then represent that now gas flow is about 2.2m
3/ H, makes user can understand the combustion gas air consumption of burnt gas wall hanging furnace in real time.
Unit interval T1 in the present invention, unit interval T2 can get identical numerical value, also can get different numerical value.The concrete time can be 3 seconds, 5 seconds, 10 seconds, 3 minutes, 5 minutes or 10 minutes etc., determines according to concrete setting demand.
