Pulverized coal fired boiler

The new type of high efficiency, energy saving and environmental friendly pulverized coal boiler adopts the advanced technologies of centralized coal preparation, precision powder supply, air fractional combustion, desulfurization in the furnace, heat exchange of water pipe (or boiler shell) boiler, efficient bag dust removal, flue gas desulfurization and automatic control in the whole process, realizing the efficient operation and clean discharge of coal-fired boilers.

[comparison of pulverized coal boiler and traditional chain furnace technology]

(1) the core technology is pulverized coal combustion

There are more than 500,000 coal-fired industrial boilers in China, more than 80% of which are chain boilers with low operating efficiency, burning crushed coal with different particle size, resulting in the average operating efficiency of coal-fired industrial boilers in China is only 60% ~ 65% at present.

And what pulverized coal boiler USES is the bituminous coal with the granularity below 200 meshes after the process of selecting, washing coal, drying, fine grinding and so on.The combustion of this kind of pulverized coal in a pulverized coal boiler can effectively improve the thermal efficiency of the boiler.

(2) no waste of fuel in the braised furnace with on-off and on-off operation

Chain boiler ignition operation time is long, if there is no load in a short time, the operation of the stewing furnace is adopted, which results in a part of fuel coal waste

The cold ignition time of pulverized coal boiler can be completed in dozens of seconds, which can be started and stopped at the same time.

(3) system integration and equipment integration

Chain boiler body and auxiliary machinery are generally purchased and used separately

The new pulverized coal industrial boiler system is a system technology and complete set of equipment, including combustion system, pulverized coal storage and transportation system, flue gas treatment system, control system, etc.
