According to finite element segmentation principle, by combining test with observation, the author has measured the air streamline and speed distribution of burning equipment in dally situation, which provides some guide for research of air field in hearth on cold and hot conditions. and the law is found of air speed distribution by measuring its speed and distribution of upper and lower deck on cold condition, thus it lays the foundation for analysis on hot condition. under four burning states, we measure the air speed in single, double - deck, and find out its corresponding distribution law
5 .根據有限元分割原理布置測點,採用降溫方法,用k五江9106等儀器分別測出單雙爐
排燃燒方式4種不同工況下,該燃燒設備爐膛內coz 、 02 、 co氣體濃度,並找到了隨爐膛高度方向及深度方向變化規律;從燃燒原理分析評價了2種燃燒方式爐膛內coz 、 02 、 co氣體濃度場分佈特點及相應燃料層內乾燥、干餾、氧化、還原、

排燃燒方式爐膛中c02 、 02 、 co氣體濃度場分佈合理性,從燃燒理論找出了最佳濃度場分佈狀態及燃料層內各反應層厚度。
After the ventilator is started, the dust catcher is under negative state and will absorb air with dust in the ductwork to the case on the dust catcher, then the air current will enter into the upper side of filter bag flowing from upper side to lower part ; most of the dust will come out from the filter bag under function of gravity and inertia and then fall into the lower case ( ash hopper ), then the clean air will enter into the air via ventilator
當通風機啟動后,除塵器便處于負壓狀態,並將余風管中的含塵空氣吸入到除塵器上箱體內,然後氣流進入濾袋上口自上而下流動,多數粉塵顆粒在重力和慣性力的作用下穿出濾袋下口,沉降至下箱體內(
灰斗) ,被濾的凈化氣體經通風機
排入大氣中。
High temperature resistant measure is taken to extend its service life significantly in comparing with the tube still hot air furnace, whereas, cross brushing of heat sink by the smoke and negative pressure smoke exhaust are used to ensure a clean heat exchanging position with stable thermal performance

During wheat and barley bred in winter in sanya, some technological characteristics concerned must be wielded according to the ecological conditions there. 1 ) carefully select materials and avoid planting the materials that can not head in sanya. 2 ) cultivated measure : spread lime before ploughing ; and make furrows during soil preparation. spread funandan in sowing furrows. after every irrigation and heavy rains, surplus water must be drained off immediately and soil must be intertilled in time. it is also a key measure in breeding in winter to prevent and eliminate the plant disease, pest and mice during plant growing period. 3 ) the flowering period of parent for hybridization must be adjusted. 4 ) the criterion for each trait selection to breeding materials should be soften to different degrees
