A pneumatic trough is a piece of laboratory apparatus used for collecting gases, such as hydrogen, oxygen and nitrogen. Pneumatic troughs require a liquid such as water. Scientists also have used mercury in pneumatic troughs, but usually only for the collection of water-soluble gases. Health-and-safety issues surrounding mercury generally prohibit its use in modern-day pneumatic troughs.

Burner with balanced air distribution includes fuel gas seat with pipe of mixing wind being installed on base, and inner fire cover and outer fire cover setup above the fuel gas seat. Outer and inner annular air grooves are setup in seat cavity of the fuel gas seat. Fuel gas channel is setup between outer and inner annular air grooves. There are outer air mixing channels between two adjacent fuel channels, and isolated from fuel gas channels. Inner air mixing channels are setup between outer air mixing channel and inner fire cover. Inner air mixing channels make air possible to enter to central area of the inner fire cover from outer air mixing channels. Thus, the invention overcomes disadvantages of deficient burning caused by not even mixing ratio between fuel gas and air in inner fire cover of traditional burner. Interconnected structure designed for structure of inner and outer air mixing channels is more in favor of balanced matching so as to raise thermal efficiency.

The invention relates to an electric propelling engine gas distributor, relates to the problem that whether propellant gas distribution of an electric propelling engine is uniform or not and belongs to the field of electric propelling. Due to non-uniform distribution of gas inlet pipelines, traditional gas distributors cause non-uniform circumferential distribution of propellant gas in electric discharging channels, and consequently, electric discharging of thrusters is affected. In order to solve the problem, the gas distributor with circumferential and radial gas transmission grooves and non-uniform distributed axial gas transmission holes / grooves is designed. The gas distributor mainly comprises a distributor-upper bottom, a distributor-lower bottom, gas inlet pipes and fastening screws. By forming gas transmission grooves, circumferential and radial diffusion of the propellant gas are manually inhibited, and non-uniform axial gas transmission holes / grooves are formed according to the different propellant gas densities in the different positions, so that the propellant gas enters the electric discharging channels more uniformly and the uniform and stable neutral particle environment is provided for the thrusters.
