Abstract
The invention provides a combined cycle power generation system of a coal firing turbine; the system is suitable for the current energy situation of being rich in coal and insufficient in natural gas in our country; a power generation device of the coal firing turbine taking raw coal as fuel is developed by applying multiple new technologies such as pressurized pulverized coal spray combustion, plasma gasification ignition, classification type low-NOx combustion, and liquid dust melting separation slagging. The coal firing turbine is different from a conventional gas turbine, is an internal combustion type power machine which uses the fire coal to replace gas and enables energy of the fuel (the coal) to be converted into useful work, and can be used for generating electricity. The power generation device of the coal firing turbine is superior to an existing steam turbine generator unit, the utilization rate of the coal is increased, and the power generation cost is greatly reduced.
Description
Technical field
The present invention relates to a kind of fire coal wheel machine formation for generating electricity, belong to power-saving technology aspect in novel firepower power field.
Background technique
Thermal power generation is to utilize the resulting heat energy power-generating of combustion fuel (coal, oil and goods, rock gas etc.).The generator set of thermal power generation has two kinds of principal modes: utilize boiler to produce high temperature and high pressure steam impulsion steam turbine and rotarily drive generator generating, be called Turbo-generator Set; Combustion gas or oil enter gas turbine heat energy are directly converted to the generating of mechanical energy driving generator, are called Gas Turbine Generating Units.The main dynamics equipment of China is steamer at present, and its thermal efficiency is lower.And gas turbine is because it has the many merits such as lightweight, starting is fast, equipment simply, does not need large water gaging, the construction period is short, developed in recent years comparatively fast, in the fields such as aviation, generating, naval vessel, oil development and conveying, occupy absolute superiority.But the main fuel using due to gas turbine is fuel oil and gas, the expensive application that has limited it.If adopt coal derived fuel as the fuel (being called coal-fired turbine) of gas turbine, make its application and application area obtain widening, generating efficiency is better than conventional Turbo-generator Set.The microfine coal coal derived fuel adopting for this device, plasma gasification combustion technology, make coal-fired turbine business application become possibility.
Summary of the invention
The present invention is applicable to the Energy Situation of the rich coal of China, poor rock gas, by using the combustion of supercharging pulverized coal injection, plasma ignition, classification low NOx combustion, liquid dust melts the multinomial new technologies such as separating slag, develops a kind of fire coal wheel machine and power generation system thereof that coal is fuel of take.Different from conventional gas turbine, with fire coal, replaced combustion gas, the energy of fuel (coal) is changed into the internal combustion type dynamic power machine of useful work, be the wheeled heat engine of a kind of pivoting leaf.Be better than existing Turbo-generator Set, improve the availability of coal, greatly reduce cost of electricity-generating.Feature of the present invention: different from conventional gas turbine, with fire coal, replaced combustion gas.The availability that improves coal, greatly reduces cost of electricity-generating; Utilize plasma gasification firing mode and supercharging coal combustion technology, toggle speed but also improve combustion efficiency has not only guaranteed to light a fire; Adopt liquid dust to melt separation and deslagging technique, effectively control combustion machine dust content, guarantee that combustion machine normally moves.Adopt air stage feeding grading combustion technology, can improve combustion efficiency and effectively control NOx discharge;
