This invention discloses a dual-material multi-row metering and loading mechanism, including a hopper, a guide trough plate, a metering tube, and a mounting bracket. The hopper, guide trough plate, and metering tube are all mounted on the mounting bracket. The hopper stores two types of materials. The guide trough plate is located below the hopper and has several funnel-shaped guide troughs. Adjacent guide troughs are used to collect the two types of materials falling from the hopper. Each guide trough has a through hole at its bottom. The top of the metering tube is inserted into the through hole at the bottom of the guide trough, allowing the material in the guide trough to flow into the metering tube for metering. The metering tube has a discharge pipe for discharging material. Two adjacent metering tubes form a group, and the discharge pipes on the same group of metering tubes converge towards the center. This dual-material multi-row metering and loading mechanism can simultaneously meter and discharge two types of materials.

The application discloses amino acid yield related protein pyrG and a biomaterial and application thereof, and belongs to the technical field of biotechnology. The problem to be solved by the application is to regulate the amino acid yield of microorganisms, and the amino acid can be L-threonine, L-tryptophan, L-arginine and L-valine. The protein is any one of the following proteins: A1) a protein with an amino acid sequence in which aspartic acid at the 450th position of sequence 2 is replaced by a sequence of histidine, serine, glycine, alanine, valine or phenylalanine; A2) a protein with more than 80% identity with the protein shown in A1) and having the function of regulating the amino acid yield of microorganisms, which is obtained by substitution, deletion and / or addition of amino acid residues on the amino acid sequence of A1); and A3) a fusion protein with the same function, which is obtained by connecting a label to the N terminal and / or C terminal of A1) or A2). The substance for regulating the expression of the pyrG protein gene can be used for regulating the amino acid yield of microorganisms or breeding of an amino acid yield strain.

The invention discloses an integrated fused salt steam generator suitable for flexible operation of a coal-fired unit. Comprising a feed water inlet, a steam outlet, a fused salt inlet, a fused salt outlet, a shell, a preheating section baffle, a porous connecting pipe plate, a steam storage chamber baffle, a porous connecting pipe plate, an electric control valve, an overheating section baffle, a fused salt pipeline, a fused salt pipeline valve, a straight pipe, a preheating section, an evaporation section, a steam storage chamber, an overheating section, a spiral pipe and a fused salt branch inlet. The heat exchanger has the advantages that the preheating section, the evaporation section and the overheating section are integrated in the heat exchanger, the occupied space of equipment is reduced, and rapid load response is achieved; the fused salt branch can adjust the temperature of a fused salt outlet and prevent the fused salt temperature from deviating from a set value; reverse flowing and alternate reversing of cold and hot fluid are combined, the water supply vaporization space is enlarged, and the flow instability phenomena such as density wave oscillation are restrained; a steam storage chamber is arranged between the evaporation section and the overheating section, the steam yield can be rapidly changed by adjusting pressure through a valve, and the requirement for flexible operation of a coal-fired unit is met.
