Description
Technical field:
The present invention relates to the coal combustion catalyst technical field, relate in particular to a kind of coal combustion catalyst for heat-engine plant and preparation method thereof.
Background technology:
Coal not only occupies bigger proportion in the energy consumption structure in the world, and in global Economic development, also plays a part very important.Along with expanding economy, its consumption is in continuous increase, and the store content of raw coal is very limited, in the production application of reality, goes back ubiquity and the utilization ratio of coal lowlyer, waste comparatively serious problem, causes very anxiety of coal resource.
Thereby, effectively, the reasonable use existing resource, improve the thermo-efficiency of coal, alleviate the emphasis that environmental pollution etc. becomes people's research.For this reason, people improve coal-fired problem from two aspects usually: being to carry out physical modifications on the one hand, mainly is that the appliance arrangement to coal combustion improves, and the structure that is used in the equipment such as boiler of coal combustion more meets the needs of coal perfect combustion; Another side is that chemistry improves, and adds certain catalyzer in the different steps of coal combustion, carries out chemical reaction through catalyzer and coal, makes coal combustion complete thereby reach, and improves the effect that heat is imitated.At present, especially use coal to thermal power plant, ature of coal itself is had very high requirement, require coal to reach more than 5 kilocalories usually at least, coal resource is already very limited, but the coal of quality better lacks especially, thereby the research of low grade coal, and is extremely urgent especially.People have also carried out some researchs to coal combustion catalyst, are ZL 0106347.9 like the patent No., and patent documents such as ZL981007116 disclose some combustion-supporting agent for fuel coal, and are higher but they all exist cost of manufacture, and the combustion-supporting time is short, the big deficiency that waits of consumption.
Summary of the invention:
The objective of the invention is to be the deficiency described in the solution background technology, and a kind of coal combustion catalyst for heat-engine plant easy, with low cost, that thermo-efficiency is high for preparing is provided.
