Abstract
This invention relates to a quick steam generator for ships, comprising a heat exchanger, a steam-water separator and a combustion system, wherein the combustion system includes a burner; the heat exchanger adopts a coil pipe device consisting of serially connected coil pipes; upper part of the coil pipe device is set with a convection heated surface constituting of plural layers of flat coil pipes in shape of mosquito incense; lower part of the coil pipe device is closely collided with a coil pipe in shape of helical spring to constitute a cylindrical combustion room; top of the coil pipe device is set with a cold water inlet; bottom of the coil pipe device is set with a water-steam mixture outlet; the burner is arranged below the coil pipe device, the cold water inlet is connected with awater pump; further, the water-steam mixture outlet is connected with the steam-water separator. Accordingly, this invention provides a steam generator which is small in dimension, light in weight, h igh in steam generation speed, stable in steam pressure, high in steam quality, safe, reliable, without explosion danger, convenient for operation/maintenance and high in heating efficiency.
Description
(1) technical field
The invention belongs to boats and ships with the boats and ships boiler plant in the plant equipment field, be specifically related to a kind of quick steam generator for ships.
(2) background technology
At present shipping industry is increasing to the demand of steam, require more and more higher, boats and ships with boiler, steam generator aboard ship use strict, requirement can stable operation under the situation that tilts, waves, produce steam and want fast, it is high that security performance is wanted, no explosion danger.The basic conventional boiler form that adopts in the prior art, volume is big, and weight is big, and it is slow to rise vapour, and efficient is low.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of heat energy utilization rate height, and is safe and reliable, no explosion danger, and volume is little, and is in light weight, and it is fast to rise vapour, and operating maintenance is easy, is suitable for the steam generator that the boats and ships condition is used.
A kind of quick steam generator for ships, comprise heat exchanger, steam-water separator and combustion system, described combustion system comprises burner, described heat exchanger adopts the coil device that is in series by coil pipe, coil device top constitutes convection heating surface by the flat coil pipe of multilayer mosquito-repellent incense shape, the coil device bottom is closely offseted by the coil spring shape coil pipe and constitutes cylindrical combustion chamber, and the coil device top is provided with cold water inlet, and the coil device bottom is provided with the gas-vapor mix outlet; Described burner is positioned at the coil device below, and described cold water inlet connects water pump, and the gas-vapor mix outlet connects steam-water separator.
Preferably, described water pump is a diaphragm type oil pressure actuated water pump.
Preferably, described steam-water separator inside is provided with the spiral separation blade that steam is separated.Blade utilizes centrifugal action, and the moisture content in the steam is separated, and becomes the saturated vapor of high mass dryness fraction.
Preferably, on the described steam-water separator steam security valve, thermometer and Pressure gauge are installed.In case temperature, pressure is too high, will cut off boiler operatiopn automatically, the safety of protection steam generator.
Preferably, on the described coil device temp probe is installed.In case the coil pipe overtemperature, fuel shutoff supply immediately, the protection coil pipe, thus the security performance of steam generator is improved greatly.
Preferably, in the described combustion system, burner is connected oil pump through the big fire fuel tap with little kerosene valve respectively, and burner also connects air blast through air door.
Preferably, described heat exchanger, steam-water separator, combustion system and water pump are connected same electric control gear.
Preferably, described coil device is selected GB/T5312-1999 boats and ships seamless steel pipe for use.
This steam generator is to burn formula in the end, and flue gas flows from bottom to top, and water flows from top to bottom, and flue gas becomes the adverse current state with water, and the temperature and pressure maximum of formation is so the thermal efficiency is the highest.
Quick steam generator for ships of the present invention is with respect to the boats and ships boiler of other form, and floor space is little, and is in light weight, raw materials consumption is few, processing ease, full-automatic programme-control, easy to maintenance, steam pressure control is reliable and stable, and load regulation rate is big, adopt the stagger arrangement reverse flow technique, the heat transfer efficiency height, the flow direction of water is the single channel direct current, no water level control, steam produces fast, from cold start, only needed 3 minutes just can reach specified steam pressure, other boiler is wanted fast about 10 times relatively.The invention provides a kind of volume little, in light weight, steam fast, steam pressure stable, high, safe and reliable, the no explosion danger of steam quality, operating maintenance make things convenient for the steam generator that the thermal efficiency is high.
