In Salar light-gathering heat utilization mode, the steam quality that trough type solar heat-collector produces approaches the used steam of thermal power plant's Auxiliary Steam most.The solar energy of new forms of energy type is introduced traditional coal fired thermal power plant Auxiliary Steam; Be not merely the energy saving for power plants transformation and proposed new thinking; Can realize simultaneously the scale utilization of solar energy; Reduce each item pollutant and greenhouse gas emission, overcome because of Changes in weather cause solar energy intermittent can not be continuously, deficiency such as stable electric generation.
The utility model content
The purpose of the utility model is that the coal fired thermal power plant energy consumption is high, contaminated environment in order to solve, and deficiencies such as unstability in the solar energy thermal-power-generating and discontinuity, and a kind of solar energy and coal fired thermal power plant Auxiliary Steam integrated apparatus are provided.
Solar energy and coal fired thermal power plant Auxiliary Steam integrated apparatus; This device comprises auxiliary steam header and solar energy heating steam generator; The steam (vapor) outlet of solar energy heating steam generator is connected to the inlet of the auxiliary steam header of thermal power plant's Auxiliary Steam through steam converter valve and automatic regulating valve door; The outlet of auxiliary steam header is connected to the hydrophobic inlet of solar energy heating steam generator through solar energy heating steam generator hydrophobic valve; The inlet of auxiliary steam header also links to each other with the outlet of former auxiliary steam steam source pipe road valve; The outlet of auxiliary steam header also links to each other with the inlet of auxiliary steam header hydrophobic valve, and the outlet of auxiliary steam header hydrophobic valve is connected to thermal power plant's condenser standpipe inlet, and the steam (vapor) outlet of auxiliary steam header is connected to auxilliary vapour user.
Said solar energy heating steam generator is generally trough type solar heat-collector.
Said solar energy heating steam generator is equipped with actinometer.
Operation principle is: when solar radiation is sufficient, cut off thermal power plant's former auxiliary steam vapour source steam supply, the steam that the solar energy heating steam generator produces is as auxiliary steam vapour source, to supply with the auxiliary steam header.When solar radiation is not enough,, realize the two complementary operation, to supply with the auxiliary steam header through regulating solar energy heating steam generator and former auxiliary steam vapour source simultaneously.When evening or solar thermal collector fault, switch tempering power plant former auxiliary steam vapour source, return to former thermal power generation operating mode.
The beneficial effect of the utility model is: Auxiliary Steam that the utility model has adopted solar energy heating steam generator and thermal power plant auxiliary steam vapour source to combine has solved that the solar energy thermal-power-generating mode directly depends on season and weather and the intermittence and the instability problem that cause; Saved construction large solar accumulation of heat facility, reduced investment outlay.This kind mode has also made full use of advantages such as conventional coal-fired thermal power generation is low-cost, power is big, has complementary advantages with solar energy, realizes traditional coal-fired thermoelectricity and solar energy complementary operation, for traditional coal fired thermal power plant reducing energy consumption provides new thinking.

The specific embodiment
Following embodiment can make those skilled in the art more comprehensively understand the utility model, but limits the utility model never in any form.
Embodiment 1:
Like Fig. 1; Solar energy and coal fired thermal power plant Auxiliary Steam integrated apparatus; This device comprises auxiliary steam header 1, auxiliary steam header hydrophobic valve 3, solar energy heating steam generator hydrophobic valve 5, solar energy heating steam generator 6, steam converter valve 8, automatic regulating valve door 9 and auxiliary steam steam source pipe road valve 10; The steam (vapor) outlet of solar energy heating steam generator 6 is connected to the inlet of steam converter valve 8; The outlet of steam converter valve 8 is connected to the inlet of automatic regulating valve door 9; The outlet of the outlet of automatic regulating valve door 9 and thermal power plant former auxiliary steam steam source pipe road valve 10 is connected to the inlet of the auxiliary steam header 1 of thermal power plant's Auxiliary Steam; The outlet of auxiliary steam header 1 is connected to the inlet of solar energy heating steam generator hydrophobic valve 5 and the inlet of auxiliary steam header hydrophobic valve 3; The outlet of solar energy heating steam generator hydrophobic valve 5 is connected to the hydrophobic inlet of solar energy heating steam generator 6, and the outlet of auxiliary steam header hydrophobic valve 3 is connected to thermal power plant's condenser standpipe inlet 4, and the steam (vapor) outlet of auxiliary steam header 1 is connected to auxilliary vapour user 2.Actinometer 7 is installed on the solar energy heating steam generator 6.
