Description
Technical field
The present invention relates to steam generator technical fields, specifically, being related to a kind of heating unit and including the heating list
The steam generator of member.
Background technology
Steam generator is the important component of Steam Power Equipment, is to utilize the thermal energy of fuel or other energy water
It is heated as the mechanical equipment of hot water or steam.
Existing steam generator generally use boiler form, the boiler of this kind of form when heated, in order to reduce thin-walled
The thermal stress of pipe and the commissure between thick wall shell and tube sheet is concentrated, it is necessary to slowly be heated to boiler, this is allowed for
Existing boiler starts to steam output from cold pot and needs to take a substantial amount of time and (be at least 40 minutes), this brings for user
Great inconvenience.
A kind of flash steam generator is disclosed in the patent document of Publication No. " CN201513874U ", although can
The speed of steam generation is greatly promoted by way of coil pipe heating, but its defect is also more apparent, includes mainly：
1, its internal combustion chamber is closely to be offseted to constitute by coil spring shape coil pipe 5, in order to ensure to be sprayed at combustor
Flame can preferably the lower part of coil device be heated and be burnt after high-temperature flue gas can be preferably to coil pipe
Device top is heated, and should be used with regard to the fuel at demand combustor can have larger specific flame spread in burning
The high-grade fuel at angle, this just greatly improves operating cost；In addition, coil spring shape coil pipe 5 closely offsets, heated
When can be expanded, this has just buried serious security risk；
2, the inside of its heat exchanger 1 is entirely connected to, i.e., at runtime, heat exchanger 1 is entirely a high pressure coil pipe,
And the volume of heat exchanger 1 is bigger, the attainable hydraulic pressure upper limit of the inside of heat exchanger 1 institute is bigger and pressure be also more difficult to carry out it is fast
The adjusting of speed, this just considerably increases the risk of the explosion of heat exchanger 1.
