Abstract

A coal injection system for a 600t / d Swiss Maerz coal kiln is transformed into a barn pump-free type energy continuous conveying system. A rotating air-locking type pulverized coal feeder is adopted by a sending system thereof for sending powder to a powder accurate measuring device; the instant and accumulated mean quality fluxes of small-flow coal powder can be monitored on-line; a coal powder conveying system is greatly simplified; more equipment and related accessories are saved; and the constructing, maintaining and managing costs are greatly lowered.

Description

technical field

[0001] This patent relates to the technical field of a pulverized coal injection system for a Swiss coal-fired Maerz kiln. Background technique

[0002] The coal-fired Maerz kiln originally used the warehouse pump type pneumatic powder feeding system and the weight loss method to intermittently monitor the small flow powder feeding system. The operation mode makes the pulverized coal injection system complicated, resulting in a substantial increase in initial investment and operating costs and a waste of energy. Contents of the invention

[0003] The purpose of this patent is to change the operating mode of the Swiss coal-fired Maerz kiln, which originally used a warehouse pump type intermittent pneumatic conveying system and adopts a weightless method to intermittently monitor small flow powder feeding, into a continuous type without a warehouse pump Pneumatic injection pulverized coal system is used to overcome some disadvantages of the warehouse pump ty...
