Abstract
The utility model relates to a direct burner of LNG. The sealed fixed combustion -supporting in the combustor of " U " type bottom, the fixed decompression heating coil of combustor inner chamber, decompression heating coil fall into the combustion air chamber with the inner chamber of combustor and communicate with each other through check valve, choke valve and the LNG seal of tube with burning chamber, decompression heating coil's entry, decompression heating coil's export through the return bend seal stretch into the combustion -supporting in, the combustor have and enter the mouth with the combustion air communicating combustion air in chamber. It need not dedicated gasification equipment, and is easy and simple to handle, and safety drops into for a short time.
Description
Technical field
This utility model belongs to a kind of burner, particularly a kind of direct burner of LNG.
Background technology
In modern society, LNG is widely used as clean energy resource, but LNG uses and needs a whole set of gasification voltage adjusting device, and equipment investment is big, limits many users.
Summary of the invention
In order to overcome the shortcoming of prior art, this utility model provides a kind of direct burner of LNG, and it is without special equipment for gasification, easy and simple to handle, safety, puts into little.
The technical scheme in the invention for solving the technical problem is: the burner base of " U " type seals fixing combustion-supporting, burner cavity fixed decompression heating coil, the inner chamber of burner is divided into combustion air chamber and combustion chamber by heating under reduced pressure coil pipe, the entrance of heating under reduced pressure coil pipe is communicated with the LNG seal of tube by check-valves, choke valve, the outlet of heating under reduced pressure coil pipe is stretched in combustion-supporting by trap seal, and described burner has the combustion air inlet communicated with combustion air chamber.
This utility model is without special equipment for gasification, easy and simple to handle, safety, puts into little.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is this utility model first embodiment schematic diagram；
Fig. 2 is this utility model the second embodiment schematic diagram.
Detailed description of the invention
Burner 6 sealed bottom of " U " type fixes combustion-supporting 5, burner 6 inner chamber fixed decompression heating coil 8, the inner chamber of burner 6 is divided into combustion air chamber 7 and combustion chamber 9 by heating under reduced pressure coil pipe 8, the entrance of heating under reduced pressure coil pipe 8 is communicated with LNG pipe 1 sealing by check-valves 4, choke valve 2, the outlet of heating under reduced pressure coil pipe 8 is sealed by bend pipe 3 to be stretched in combustion-supporting 5, and described burner 6 has the combustion air inlet 11 communicated with combustion air chamber 7.
As shown in Figure 1, it is adaptable to diffusion type burns.Described combustion-supporting 5 is " U " type, fixes with described coaxial the sealing in the same direction of burner 6, the opening part inwall of combustion-supporting 5 fixes cowling panel 10.
As shown in Figure 2, it is adaptable to atmospheric burning type.Described helps gas apparatus 5 for goblet shape, stretch into the upper sealing fixed nozzle 15 of the bend pipe 3 mouthfuls in combustion-supporting 5, fixing air regulating board 16 on combustion-supporting 5 inwall of nozzle 15, help on gas apparatus 5 inwall once air intake 14 near air regulating board 16, combustion-supporting 5 has mixing chamber 13 and burner mouth 12.
The air of the entrance of described primary air entrance 14 and nozzle 15 spray LNG gasification after natural gas realize premixing, the primary air ratio that part is pre-mixed is 0.4-0.8.Realize by regulating air regulating board 16.
Ignition method of the present utility model is: utilize external heat to carry out initial LNG gasification pressure regulation and burning.Such as with a small amount of fuel oil, ethanol, or initial natural gas is lighted in electricity consumption heating, enables the LNG that gasification is follow-up, can reach the purpose of continuous burning.
