Abstract

The invention relates to the technical field of conversion of carbon-containing substances such as coal and biomass, in particular to an ash column preparation device and method. The ash column preparation device is composed of a support, an objective table, a pressure rod, a circular pipe, a supporting rod and weights with different masses, wherein the supporting rod is fixed to the support. Whenan ash column is prepared, weights with different masses are added to the objective table to control the preparation pressure of the ash column. The equipment for preparing the coal and biomass carbon-containing substance ash column under the certain pressure is simple, convenient to operate, high in pressure control accuracy and wide in application range, and has obvious advantages in the aspectof preparing the ash column under the certain pressure to measure the sintering melting characteristic of ash.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of conversion of carbonaceous substances such as coal and biomass, in particular to an ash column preparation device and method. [0003] (2) Background technology [0004] Ash sintering and melting flow characteristics are important indicators for the clean conversion (combustion and gasification) of carbonaceous substances such as coal and biomass. During the conversion process, due to the inadaptability of the ash fusion characteristics of coal and other carbonaceous substances, the efficiency will drop, slagging and equipment corrosion will even lead to the shutdown of the entire conversion system. In order to determine the operating temperature for the conversion of carbonaceous substances such as coal and biomass and to accurately control the ash fusion characteristics of carbonaceous substances such as coal and biomass, the accurate determination of the ash fusion temperature of carbonaceous...
