For a slow-burning mixture (10% hydrogen in air), the pressure is reduced when the discharge holes are far from the local burning region. A study has been made on the joint effects of immobile alternating obstacles and gas-dynamic perturbation caused by the motion of the medium towards the...
Carbon in methane is oxidized D. Hydrogen in methane is oxidized 相关知识点: 试题来源: 解析 C。解析:甲烷燃烧的反应方程式为CH₄ + 2O₂ = CO₂ + 2H₂O。在这个氧化还原反应中,甲烷中的碳元素化合价从 - 4升高到 + 4,失去电子被氧化。氧化还原反应的本质是电子的转移,化合价升高的元素被...
In this context, one such preparation is denture cleaner in which the major toxic component is sodium perborate which decomposes to form hydrogen peroxide and sodium borate. These products are strongly alkaline and very irritating to the skin and mucous membranes thus can produce dermal toxicity...
1. The Sun is the heart spot of the Solar system which is the source of energy of all organism of the earth. 2. The innermost layer of the Sun is called Corona. Which of the above statement(s) is/are correct? View Solution
The laminar burning velocities of hydrogen–air and hydrogen–methane–air mixtures are very important in designing and predicting the progress of combusti... M. Ilbas and A.P. Crayford and İ. Yılmaz and P.J. Bowen and N. Syred - 《International Journal of Hydrogen Energy》 被引量...
The ratio of turbulent to laminar burning velocity correlates well with both the turbulent Reynolds number and the ratio of laminar burning velocity to r.m.s. turbulent velocity. The use of hydrogen-air mixtures has extended the data on premixed turbulent combustion to regimes with higher values ...
Using nitrogen and carbon dioxide as diluents, a reduction of rate of flame spread with reduction... DJ Rasbash,B Langford - 《Combustion & Flame》 被引量: 28发表: 1968年 On board hydrogen producing fuel cell technology(elements) coil and plate system used separately or in combination to ...
responding value for pure methane/air flame According to these results when hydrogen is added to methane, a linear increase of the laminar burning velocity occurs with increasing the hydrogen mole fraction in the fuel (X H 2 ) up to values equal to about 0.7. Furthermore, the en- hancem...

Nitrogen is obtained by burning hydrogen in air. The operating condition use high temperature about 450-500°C and high pressure about 80-90 bar. The reaction mixture is cooled so that the ammonia is liquefied and removed. The remaining nitrogen and hydrogen are recycled. The overall reaction ...
