Description
Technical field
The invention belongs to regenerated resources energy transformation technology fields, and in particular to a kind of regenerated resources electricity generating method by burning.
Background technique
The method of regenerated resources power generation by waste combustion is to carry out high temperature incineration to resources such as the higher rubbish of fuel value (also thoroughly to disappear
It has gone out pathogenic organisms and corrosivity has confidential object).The thermal energy generated in high temperature incineration (smog of generation is by processing) turns
High-temperature vapour is turned to, rotating turbine is pushed, produces electricl energy generator.In order to reach higher energy transformation ratio and again production-goods
The effect thoroughly burned in source needs regenerated resources that can fully burn in burning phase.For this purpose, need to avoid the occurrence of as far as possible again
The case where production-goods source is accumulated in incinerator.
The material pusher of existing incinerator design is too simple, can only integrally push ahead regenerated resources, hold
It easily leads to regenerated resources and is accumulated at one higher, be unfavorable for its completely burned, affect the conversion ratio of energy.Regenerated resources simultaneously
Accumulation to may also lead to the uniformity of the abundant degree burnt in incinerator at any time poor, thermogenetic steam is changed in influence
Uniformity, and then influence the efficiency of power generation.

Picture forms two-dimension temperature image；
[2] the two-dimension temperature image obtained according to step [1], judges in fire grates at different levels, the normal fire grate grade of ignition temperature
The excessively high fire grate series of the too low fire grate sum of series ignition temperature of number, ignition temperature；
[3] according to step [2] obtain as a result, to the normal fire grate of ignition temperature without additional operation, only with
Scheduled intake velocity and material pushing speed；The fire grate too low to ignition temperature carries out additional supply gas；To ignition temperature mistake
High fire grate carries out additional agitation operation.
After the technical solution, it can be classified by the information fed back to temperature detection to fire grates at different levels,
Then additional operation is carried out to low temperature in two-dimension temperature image and high-temperature region, the purpose is to finally to regenerate on fire grates at different levels
The case where burning of resource is more uniform, avoids the occurrence of material accumulation.So that the converting heat rate of regenerated resources and power generation
It is more efficient.
Preferably, in step [1], also using the combustion case of regenerated resources on optical camera observation fire grate, pass through mesh
The fire grate that discovery material accumulation is more than predetermined altitude is surveyed, additional agitation operation is also carried out.After the preferred embodiment, Neng Goujin
The case where one step judges material accumulation on fire grate by the visual aids of optical camera.
Preferably, the temperature detection in step [1] is carried out by being arranged in the non-contact temperature sensor of array, each
Grade fire grate is correspondingly arranged at least two non-contact temperature sensors.In the preferred embodiment, every level-one fire grate is carried out
Corresponding temperature detection to obtain the real time temperature of every level-one fire grate, and then obtains the mode of operation to every level-one fire grate, phase
For the prior art, this mode that detects and controls is specific to every level-one fire grate, more finely.
