Many enterprises add this industry, and the heat recovery technology gradually tending to ripe also provides thinking for solution UTILIZATION OF VESIDUAL HEAT IN.
Waste heat boiler is that the high-temperature flue gas utilizing upstream equipment to produce carries out heat exchange production steam or hot water with working medium
Equipment.But current most of engineering does not has high-temperature flue gas at the initial stage of going into operation to be produced, and upstream equipment fluctuation of service
In the case of the high-temperature flue gas that produces tend not to meet the requirement of waste heat boiler, thus cause waste heat boiler fluctuation of service.
Utility model content
For the problems referred to above, this utility model provides a kind of vertical supplementary fired Waste Heat Boiler, and it can solve existing waste heat
Boiler upstream equipment without high-temperature flue gas supply or high-temperature flue gas supply unstable and produce cannot meet heating demand
Problem.
Its technical scheme is, a kind of vertical supplementary fired Waste Heat Boiler, and it includes drum and vertical vertical shaft type flue, described vertical
The top of formula vertical shaft type flue is provided with gas approach, bottom is provided with exhanst gas outlet, is provided with and is subject in described vertical vertical shaft type flue
Hot side assembly, described drum is connected with described heating surface assembly by circulation line, it is characterised in that: it also includes film-type water-cooling
Wall afterburning burner hearth, described fin panel casing afterburning burner hearth lower end is provided with afterburning burner, described fin panel casing afterburning burner hearth
Top and described vertical vertical shaft type flue top UNICOM, described fin panel casing afterburning burner hearth and described vertical vertical shaft type flue top
It is provided with the first flue damper valve plate in UNICOM's section in portion, at the gas approach of described vertical vertical shaft type flue, is provided with the second flue
Gate valve plate.
Further, described heating surface assembly includes laying the most successively superheat section heating surface, the first evaporator section,
Second evaporator section, province's coal section and preheating section.
The beneficial effects of the utility model are: it is in the case of During Initial Stage Construction upstream equipment cannot provide high-temperature flue gas
By the fin panel casing burner hearth being connected with flue and arrange in the lower end of this fin panel casing burner hearth afterburning burner come
There is provided high-temperature flue gas to carrying out waste heat boiler, thus meet heating demand；The high temperature cigarette produced when upstream equipment fluctuation of service
When gas can not meet the service requirement of waste heat boiler, the high-temperature flue gas utilizing afterburning burner to produce can supplement part heat smoke
Thus meet heating demand；Therefore its strong adaptability, load stability is high；Between its film work water-evaporating furnace and waste heat boiler flue
The the first flue damper valve plate arranged controls whether enabling of afterburning system, its simple in construction, low cost, convenient to install and maintain.

Detailed description of the invention
Seeing Fig. 1, a kind of vertical supplementary fired Waste Heat Boiler, it includes drum 1 and vertical vertical shaft type flue 2, vertical vertical shaft type
The top of flue 2 is provided with gas approach 3, bottom is provided with exhanst gas outlet 4, is provided with heating surface assembly in vertical vertical shaft type flue 2,
Drum 1 is connected with heating surface assembly by circulation line；In Fig. 1,14,15 are respectively in circulation line the rising being connected with drum
Pipe and down-comer；It also includes that fin panel casing afterburning burner hearth 5, fin panel casing afterburning burner hearth 5 lower end are provided with afterburning burning
Device 6, fin panel casing afterburning burner hearth 5 top and vertical vertical shaft type flue 2 top UNICOM, fin panel casing afterburning burner hearth 4 is with vertical
The first flue damper valve plate 7 it is provided with, at the gas approach of vertical vertical shaft type flue 23 in UNICOM's section at formula vertical shaft type flue 2 top
It is provided with the second flue damper valve plate 8；Heating surface assembly includes that the superheat section heating surface 9, first laid the most successively evaporates
Section the 10, second evaporator section 11, province's coal section 12 and preheating section 13.In Fig. 1,16 for being used for supporting drum 1, vertical vertical shaft type flue 2
And the steel frame construction part of fin panel casing afterburning burner hearth 5.
Specifically describe work process the most of the present utility model below in conjunction with the accompanying drawings:
When upstream equipment normal table runs, waste heat boiler is properly functioning, closes the first flue damper valve plate 7, opens the
Two flue damper valve plates 8, upstream equipment the high-temperature flue gas produced is entered vertical vertical shaft type flue 2 by gas approach 3, washes away successively
Superheat section the 9, first evaporator section the 10, second evaporator section 11, province's coal section 12 and preheating section 13 producing steam in next life, low-temperature flue gas is through flue gas
Outlet 4 is introduced chimney by air-introduced machine and discharges；
And when the commencement of works initial stage, upstream equipment carries without high-temperature flue gas, now, open the first flue damper valve plate 7, close
Second flue damper valve plate 8, the heat smoke utilizing afterburning burner 6 burning to produce washes away fin panel casing afterburning burner hearth 5, mistake successively
