Pipe, first straight tube are connected with the drum, and second straight tube is connected with the superheater, the steam pipeline body
On be provided with temperature-adjusting device, be provided with control valve on the temperature-adjusting device, the temperature-adjusting device includes point
Netted pipe of the cloth on the steam pipeline body and the coolant inlet pipe connected with the netted pipe, the coolant
The control valve is set on input pipe.
Preferably, described superheater one end is provided with the superheater import connected with second straight tube, the superheater
The other end is provided with superheater outlet.
Preferably, steam (vapor) outlet electrically operated gate is provided with the superheater outlet.
Preferably, the first thermometer is provided with first straight tube.
Preferably, second temperature meter is provided with second straight tube.
Compared with prior art, the beneficial effects of the utility model are：
Waste heat boiler steam transmission system of the present utility model is due to being provided with temperature adjustment on steam pipeline body
Device, temperature-adjusting device includes the netted pipe being distributed on steam pipeline body and the coolant that connects with netted pipe is defeated
Enter pipe, control valve is set on coolant inlet pipe, after taking said structure, room temperature desalination is given by the regulation of control valve
Water is delivered in netted pipe, and the room temperature desalination feedwater in netted pipe carries out cooling down to steam pipeline, directly arrives drum
The temperature of the steam in superheater reduces, so as to reduce main steam temperature, meet the temperature that steam turbine needs are used, it is to avoid because
Main steam temperature is too high and cause unit forced outage, the economic loss for causing and equipment are stopped transport and cause equipment loss, also avoid
Increase unit operation cost, brings bigger economic benefit to enterprise.

In figure：1- drums, the first straight tubes of 2-, 3- steam pipeline bodies, 4- coolant inlet pipes, the netted pipes of 5-, 6-
One thermometer, 7- control valves, the second straight tubes of 8-, 9- second temperature meters, 10- superheaters, 11- superheater imports, 12- superheaters
Outlet, 13- steam (vapor) outlet electrically operated gates.
Specific embodiment
Below in conjunction with the accompanying drawings specific embodiment of the present utility model is described further.Here it should be noted that
For the explanation of these embodiments is used to help understand this utility model, but do not constitute to restriction of the present utility model.This
Outward, as long as involved technical characteristic in this utility model disclosed below each embodiment does not constitute conflict each other
Can just be mutually combined.
Fig. 1 is refer to, waste heat boiler steam transmission system of the present utility model is connected including drum 1 and with drum 1
Steam pipeline, the other end of steam pipeline are connected with superheater.Steam pipeline includes steam pipeline body 3 and sets
First straight tube 2 and the second straight tube 8 at 3 two ends of steam pipeline body is placed in, the first thermometer 6 on the first straight tube 2, is provided with, the
One straight tube 2 is connected with drum 1.Second straight tube 8 is connected with superheater 10, is provided with second temperature meter 9 on the second straight tube 8.Steam
Temperature-adjusting device is provided with conveying tube body, control valve 7 on temperature-adjusting device, is provided with.
Temperature-adjusting device includes the netted pipe 5 being distributed on steam pipeline body 3 and cold with what netted pipe 5 was connected
But liquid input pipe 4, arranges control valve 7 on coolant inlet pipe 4.
10 one end of superheater is provided with the superheater import 11 connected with the second straight tube 8, and the other end is provided with superheater and goes out
Mouth 12, is provided with steam (vapor) outlet electrically operated gate 13 at superheater outlet 12.
Waste heat boiler steam transmission system of the present utility model is by the steam pipeline between drum 1 to superheater 10
On installed the temperature-adjusting device of water additional, the vapor (steam) temperature that drum 1 enter superheater 10 can be reduced, boiler export main steam
Temperature can be adjusted within the use range that steam turbine needs, it is no longer necessary to by forced-stopping machine, can generate electricity more.
Need to adjust aperture in view of temperature control, needs are provided with control valve 7 on temperature-adjusting device and adjusted
The water yield, in order to determine the main steam temperature scope of needs, is provided with the first thermometer 6, on the second straight tube 8 on the first straight tube 2
