Off member, is fixed with combustor inlet at the top of the upper collecting chamber, the side of the combustor inlet and in the upper collecting chamber
Steam-water separator is fixed with, steam (vapor) outlet, the bottom pair of the outsourcing inner barrel are fixed with the steam-water separator
Title is provided with two lower headers, and the inwall of the outsourcing cylinder is evenly arranged with boiler tube bundle, one end of the boiler tube bundle
It is fixedly connected with the lower header, the other end of the boiler tube bundle is fixedly connected with steam-water separation part in the stove.
As a preferred technical solution of the present invention, boiler feed water mouth is fixed with one of them described lower header,
Boiler blow-off mouth is fixed with another described lower header.
As a preferred technical solution of the present invention, the side of the outsourcing cylinder is fixedly installed exhanst gas outlet.
As a preferred technical solution of the present invention, the boiler tube bundle is to be obtained by accurate thermodynamic computing in outlet pipe
What the heating power distribution of water was set.
The beneficial effect that is reached of the present invention is：
1. compared with the tubular boiler of tradition, vertical boiler booster risk is greatly reduced；
2. compare other vertical gas boilers and steam generator, it is not necessary to the outer water separator of independent stove is installed, and
Good separation, obtain high-quality steam；
3. body design ordinary water level water capacity is less than 50L, link is being used not by TSG《Boiler safety technology Supervision Code》About
Beam, make sale and use more convenient, purposes is also more extensive.

Embodiment
The preferred embodiments of the present invention are illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein preferred real
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
Embodiment 1
As shown in Figure 1-2, the present invention provides the vertical water-tube Natural Circulation steam boiler that a kind of multipurpose exempts from pot inspection, including outsourcing
Cylinder 3, upper collecting chamber 5 and lower header 2, the top of outsourcing cylinder 3 are fixed with upper collecting chamber 5, and the bottom of upper collecting chamber 5 is fixed with stove
Interior steam-water separation part 9, the top of upper collecting chamber 5 are fixed with combustor inlet 6, the side of combustor inlet 6 and in upper collecting chamber 5
Steam-water separator 8 is fixed with, is fixed with steam (vapor) outlet 7 on steam-water separator 8, the bottom inside outsourcing cylinder 3 is symmetrically set
There are two lower headers 2, the inwall of outsourcing cylinder 3 is evenly arranged with boiler tube bundle 4, and one end and the lower header 2 of boiler tube bundle 4 are fixed
Connection, the other end of boiler tube bundle 4 are fixedly connected with steam-water separation part 9 in stove.
Further, boiler feed water mouth 1 is fixed with one of lower header 2, pot is fixed with another lower header 2
Dirt removing mouth 11, facilitate the water inlet or blowdown of boiler, be advantageous to effective progress of work, be easy to use.
The side of outsourcing cylinder 3 is fixedly installed exhanst gas outlet 10, and conveniently connecting extraneous processing by exhanst gas outlet 10 sets
It is standby, it is easy to effectively handle flue gas.
Boiler tube bundle 4 is that the heating power distribution that water in outlet pipe is obtained by accurate thermodynamic computing is set, and can effectively be arranged
Independent carbonated drink down-comer, the Natural Circulation of uniqueness is formed, is easy to the progress of work.
The nominal steam amount that the invention is applied to steam boiler is respectively less than 50L for 250kg/h water capacities, specifically, work
When, air fume side：Cold air（Or preheated air）Boiler body is entered by combustor inlet 6, by transversal flow certainly
So circulation tube bank 4 is finally discharged after washing away heat exchange by exhanst gas outlet 10（Subsequent parts economizer, air heat retrieving apparatus, cold can be connected
