Description
Technical field
The present invention relates to a kind of device and method more particularly to a kind of adjusting coal gasification for adjusting coal gasifier combustion conditions
The device and method that stove fire layer burns operating condition partially belong to coal gas technology field.
Background technique
Coal is one of the main energy sources in China, and converting coal into coal gas is the preferred approach that energy is obtained from coal,
It is the main means realizing Coal Clean and efficiently utilizing.Coal gas complex technical process, in gasification furnace coal be from top to bottom, gasification
Agent is then from bottom to top to carry out countercurrent movement, chemical reaction and heat exchange occurs between the two, to be formed in furnace several
The region of a layering, oxide layer therein and reduction zone are referred to as conversion zone.In oxide layer (also known as fire bed), from ash bed
It goes up the oxygen come in gasifying agent and carbon occurs fierce burning and generates carbon dioxide, and release a large amount of heat.Ideally,
The height of oxide layer is generally 3-6 times of fuel used lumpiness, about 20-40cm, and the temperature of oxide layer about controls
1200 DEG C or so.But in practical applications, the perfect condition of oxide layer is generally difficult to obtain.It was verified that igniting when point furnace
Distributional pattern that condition, coal enter in furnace, gasifying agent enter the uniformity in furnace, can all make the big discounting of the perfect condition of oxide layer
Button even results in gasification furnace apparatus and breaks down when serious.Wherein most commonly seen failure is: since in-furnace temperature is unevenly distributed
It is even, it will form the inclined burning phenomenon that fire bed lows while height in furnace, gasification furnace cannot burn operation partially for a long time, if cannot be right
Fire bed height and temperature in furnace carry out timely adjustment, will lead in furnace " leakage charcoal ", slag blanket fusing, high temperature wash away refractory brick or
Water cooling tube etc. damages and is forced blowing out.The conventional method for avoiding above-mentioned failure is manually to drill a blasting hole, manually dial coal.Not only method is former
Begin, large labor intensity, the hot environment of operator is severe, and rectifying effect is poor, working efficiency is low, delays work, mistakes；If
The yield that can then largely effect on coal gas is solved using the slow method for burning transition, is done so clearly unworkable.Therefore, with existing
Some scientific methods implement effectively control to the combustion state of coal gasifier, are the classes that those skilled in the art need primary study
Topic.
