A premixed low-nitrogen gas boiler is provided, which includes a reversed flow-swirl mixer being opposite mixing of natural gas and air. A flow deflector is arranged at a gas mixture outlet of the reversed flow-swirl mixer. An upper flow equalizing plate and a lower flow equalizing plate are arranged below the flow deflector, the upper flow equalizing plate is positioned above the lower flow equalizing plate, and a channel for enhancing mixing of gas mixture is formed between the upper flow equalizing plate and the lower flow equalizing plate. A comb-shaped water-cooled burner is arranged at the rear end of the lower flow equalizing plate, a combustion chamber is arranged at the rear end of the comb-shaped water-cooled burner, hearth tube bundles are arranged in a ladder-shaped convergent hearth, and the hearth tube bundles form an inner loop with a working medium water-steam mixture in a hearth water tank.

A method for sorting and comprehensively utilizing municipal solid waste includes steps of: 1) feeding the municipal solid waste into a feeding tank through a feeding inlet, then outputting into a breaking device; 2) breaking refuse bags and large blocks by the breaking device; 3) transporting broken refuse into a two-stage roller screen for screening out dusts with a particle size of less than 3 mm, and hanging strips; and 4) transporting mixed refuse screened by the two-stage screen into a vibrating screen; screening oversize products by a heavy winnowing machine for separating inorganic blocks, large plastics and paper; transporting underflow products into a two-room multi-functional winnowing machine for dividing into heavy materials, light materials and medium materials. By effectively combining sorting devices, effective sorting and reutilization of mixed refuse are achieved. Thereafter, paper, fibers, plastics and kitchen organic refuse are respectively for producing refuse derived fuel, wood-plastic composite and fertilizer.
