Dual Bias Cold Flow Burner Experimental and computer simulation
Be squeezed into a thin shape. Long 75Otoni, wide 150lnnl, move back to the next channel from the nozzle 300rr Ⅱ Il, after more than half open when the shift 150lnnl (as shown in Figure ll). Thus, the waist of the ignition point of combustion air can play a regulatory role. Figure 11 waist,[link widoczny dla zalogowanych], full-time air recirculation measured with the cold calculation of three-dimensional flow characteristics very similar to the size of the recirculation zone, adjust the waist,[link widoczny dla zalogowanych], the wind can change the position and shape of the recirculation region. Theory and practice coincide. Figure 10 waist, half-open when the air recirculation momentum ratio of 4 conclusions Hot: [(c +0 .)(}) 1: (i) 2]: 1:2.10 cold and hot momentum ratio similar to ensure that the boundary conditions are similar. Burner testing single angle were measured and the flow characteristics of the burner nozzle, dual-channel Burner, the next two channels with cross-jet nozzle under the channel after amplification, making the second air flow deceleration crossing point (1) dual-channel bias combustion of coal Lao dual-channel device is the use of recirculation zone generated stable cross-jet fire, while installation of blinds in an air duct separators, so that shades into a two-phase two-channel, each far away from the stoichiometric ratio, the formation of oxidation - reduction NOx reducing atmosphere . (2) Dual Burner in the cavity of the wind set the two waist, so that the recirculation zone becomes adjustable, by the wind switches to adjust the waist size, and before and after recirculation, to adjust the point of pulverized coal ignition and combustion stability. No. 6 PROCEEDINGS OF. Dual Bias Cold Flow Burner Experimental and computer simulation. 661 (on the next 656) I6 luxuriant l3l; 3-5c Shan Twain Twain ten 25cI a 40cm soil temperature, soil temperature of a far less affected by the indoor air temperature affected by sunlight, large; the average coal consumption of each boiler 9kh,[link widoczny dla zalogowanych], on the indoor air have a significant effect of temperature and cooling to maintain the soil has a smaller magnitude. Therefore, the boiler heating a greenhouse winter production of effective protection methods. 5 Conclusion 061218246121824612182461218246121824 when cyberspace summary, prepared by VB5.0 dynamic simulation program can test the soil temperature Figure 8, a 5c Yun Shan soil soil temperature for a 25 ~ m for a 40 ~ m soil temperature well enough to simulate a greenhouse winter running a variety of conditions, for automatic control of greenhouse heating software infrastructure, greenhouse heating results further demonstrate a suitable heating method can guarantee the possibility of greenhouse winter production. With the deepening of technological agriculture, greenhouse heating research will attract wide attention, to the vigorous development. References: [1] Wang Shichun. Jiang Cheng.
