Description
Technical field
The utility model relates to pan shell type gas fired-boiler, and the combustion case in rear hearth is lighted mainly for detection of burner
Background technology
The return stroke wet back type gas boiler of horizontal internal combustion three is compact-sized due to the type of furnace small volume, easy to operate, disposably
Invest low, be greatly favored by consumers, its main flue gas flow is：Natural gas forms high temperature cigarette in corrugated internal furnace after burner is lighted
Gas, enter return combustion chamber after flue and hot water heat exchange, after return combustion chamber turns to 180 degree, enter two return through return combustion chamber front tube sheet
Smoke pipe, enter front smoke box after two return smoke pipe and hot water heat exchange, enter three backhaul smoke pipes after front smoke box turns to 180 degree, pass through
Three backhaul smoke pipes are followed by chimney discharge with entering rear smoke box after hot water heat exchange.Cold water enters shell from backwater base, and cold water is uniform
Circulate in drum, seen off with being changed into hot water after heating surface participation heat exchange through water outlet base.The problem of presently, there are be：Due to
Ignition temperature in burner hearth is high after burner is lighted, and flue gas easily generates CO, NO, NOx、SO2Deng pernicious gas, in flue
The ignition temperature distribution of each difference, the pernicious gas content distribution of each difference, the smoke components inspection of each difference
Survey particularly significant.
Utility model content
The utility model is in view of the above-mentioned problems, propose a kind of boiler that can be used in smoke test in flue.
The utility model is realized by following technical scheme, a kind of return stroke wet back type of horizontal internal combustion three combustion of tape test pipe
Gas boiler, it includes horizontal longitudinally disposed cylindric shell, and shell inner chamber middle and lower part sets flue；Flue is integrally cylindrical in shape,
The barrel of flue is continued and formed by some flat segments and some bellows segments, and some flues are provided with flue flat segments barrel
Instrument connection, the position that flue instrument connection is corresponded on shell are provided with some shell instrument connections, are surveyed in flue instrument connection and shell
It is fixedly installed testing tube in prospect hole, testing tube is anterior with inboard wall of furnace water-stop and to be welded as a whole, testing tube rear portion and pot
Water-stop and it is welded as a whole between shell outer wall；Gas detection sensor is provided with testing tube.
The specific feature of this programme also has, and the bellows segment of flue accounts for 1/3rd of flue overall length to half.
Testing tube is to be uniformly distributed from the front to the back in each flat segments.
Testing tube rear end is provided with capping.
The beneficial effect of this programme is：On the basis of the common return stroke wet back type gas boiler of horizontal internal combustion three, all-wave
Line flue is changed to the flue being made up of flat segments and bellows segment, and every section of flue is cylindrical shape, and cylindric center section is by adding
Formed after heat after ripple machine is compressed to corrugated.The corrugated portion of ripple machine pressing should be at least the 1/ of two sections of total lengths
3, it can so increase the flexibility of flue.It is assembled into after the completion of a flue and opens up flue survey thereon by mach mode
Prospect hole, correspondence position opens up shell instrument connection on shell, and perforate should ensure that testing tube is just put into, and testing tube is inserted into shell
And flue, testing tube inboard wall of furnace formed water-stop and welding formed one, testing tube shell outer wall formed water-stop and
Welding.It is overall that the water pressure test is carried out to boiler, ensure the watertightness of boiler.Gas detection sensor is provided with testing tube,
Temperature Distribution, the content of combustion product, the high-temperature flue gas speed in rear hearth are lighted for testing burner in burner hearth.
