Abstract
The utility model discloses a vehicle-mounted boiler LNG (Liquefied National Gas) combustion device. A vehicle platform is provided with an LNG storage bottle (1), a water-bath vaporizer (2), a combustor (3), a gas boiler (4), a gas power generator (5), a pressure regulating assembly (6) and a control cabinet (7). The water-bath vaporizer is matched with the combustor, and after LNG is vaporized by the water-bath vaporizer, the variation range of air pressure is small, the air pressure is easy to regulate, the combustion condition can be favorably kept stable, the safe and pollution-free combustion of the LNG for a vehicle-mounted boiler can be realized, and the effect of heating liquid in the boiler can be achieved.
Description
Technical field
The utility model relates to the boiler loaded on truck combustion technology take liquefied natural gas as fuel, especially boiler loaded on truck LNG burner.
Background technology
In the prior art, LNG refers to liquefied natural gas.General boiler loaded on truck is fuel mainly with diesel oil, crude oil or other fuel oil.The technology of now boiler loaded on truck use LNG discloses less, and wherein, how safety realizes that boiler loaded on truck acts as a fuel with LNG, is a very important key problem in technology.Just have simultaneously known automobile take LNG as fuel now, namely referred to as the LNG automobile, general minute three kinds of forms: a kind of is complete pure LNG automobile take LNG as fuel, a kind of is that LNG mixes the double fuel LNG automobile that uses with diesel oil, and the variable fuel vehicle of a kind of LNG and gasoline replacement use, its gas burning system is basic identical, all be that LNG is stored in the automobile-used LNG storage tank, be vaporizated into gas supply engine about 0.5MPa by vapourizing unit, its main composition has LNG storage tank, vaporizer, decompression pressure regulator valve, blender and control system etc.What can use for reference is could be used for burning work after LNG need to vaporize, but the energy-saving safe technology of vaporescence but can't reach desirable situation.
The utility model content
The purpose of this utility model provides a kind of boiler loaded on truck LNG burner, realizes that boiler loaded on truck uses LNG to act as a fuel normally, work safely.
Realize that the measure of the present utility model purpose comprises: LNG storage bottle, water bath type vaporizer, burner, gas fired-boiler, fuel gas generation unit, pressure regulation assembly and switch board are installed on the vehicle platform.
In the utility model, water bath type vaporizer and burner are worked in coordination, through water bath type vaporizer vaporization LNG, the air pressure change scope is little, air pressure is easy to regulate, be conducive to keep stable combustion condition, can realize that boiler loaded on truck with LNG safety, pollution-free burning, reaches the effect of liquid in the heating boiler.
Description of drawings
Fig. 1 is the utility model structural representation
Reference numeral: LNG storage bottle 1, water bath type vaporizer 2, burner 3, gas fired-boiler 4, fuel gas generation unit 5, pressure regulation assembly 6, switch board 7, three-cylinder plunger pump 8.
The specific embodiment
Below in conjunction with specific embodiment, describe:
LNG storage bottle 1 is installed, water bath type vaporizer 2, burner 3, gas fired-boiler 4, fuel gas generation unit 5, pressure regulation assembly 6, switch board 7 on the vehicle platform.
The fluid pipeline of LNG storage bottle 1 links to each other with water bath type vaporizer 2 feed liquor pipelines, water bath type vaporizer 2 pipeline of giving vent to anger links to each other with pressure regulation assembly 6 admission lines, the pipeline of giving vent to anger of pressure regulation assembly 6 links to each other with fuel gas generation unit 5 and the admission line that is installed in the burner 3 on the gas fired-boiler 4 respectively, the water inlet of water bath type vaporizer 2 links to each other with the outlet of fuel gas generation unit 5 cooling water tanks, and the water out of water bath type vaporizer 2 links to each other with the import of fuel gas generation unit 5.
The coil pipe water inlet of gas fired-boiler 4 links to each other with the water out of three-cylinder plunger pump 8.
In the utility model, the water inlet of water bath type vaporizer 2 links to each other with the outlet of fuel gas generation unit 5 cooling water tanks, and the delivery port of water bath type vaporizer 2 links to each other with the import of fuel gas generation unit 5, forms the water circulation system of a closed; The liquified natural gas of LNG storage bottle 1 is through being heated vaporization, and its heat comes from the aforesaid water circulation system that is communicated with cooling water tank, namely pass through heat exchange after, flow back to the water of cooling water tank because losing the reduction of heat temperature.
In the utility model, after the liquified natural gas of LNG storage bottle 1 is vaporized through water bath type vaporizer 2, be sent to respectively burner 3 and the fuel gas generation unit 5 that is installed on the gas fired-boiler 4 by pressure regulation assembly 6, after starting, fuel gas generation unit 5 provides electric power for burner 3, burner 3 enters duty by manual command or the auto state of switch board 7, and three-cylinder plunger pump 8 injects extraneous liquid continuously and carries by the heating of the coil pipe in the gas fired-boiler 4.
In the utility model, through water bath type vaporizer 2 vaporization LNG, the air pressure change scope is little, and air pressure is easy to regulate, and is conducive to keep stable combustion condition, can realize that boiler loaded on truck with LNG safety, pollution-free burning, reaches the effect of liquid in the heating boiler.
In above enforcement, the technology such as engine, generator operation principle and LNG burning that do not reach narration no longer describe in detail.
