Description
Technical Field
The present invention relates to a steam generating system.
Background
High temperature steam has great industrial application. The highest temperature steam on the market is generally generated by means of a boiler. The existing boiler for producing steam directly uses water pipes in a fire boiler, and the boiler with the structure has a large amount of heat discharged into the atmosphere along with flue gas, so that the heat loss is serious. And the outer surface of the water pipe is easy to deposit carbon, so that the heat transfer efficiency is poor.
In order to solve the problem, manufacturers add a set of heat exchange system on the boiler and use the waste heat of the flue gas for reheating. This approach, on the one hand, increases costs and, in addition, the heat exchanger lines are prone to clogging, and therefore improvements are desirable.

When the device is used, the atomizer atomizes water into micron-level small droplets, the micron-level small droplets enter the boiler along with air, then the small droplets are heated by the fuel layer along with ascending air flow from the lower part of the bushing plate to form high-temperature water vapor, and then the high-temperature water vapor flows out from an outlet at the upper part. According to the device, water is directly contacted with fuel, so that heat loss does not exist, a heat exchanger is not needed for collecting the waste heat of the flue gas, and the cost is greatly reduced. And a water pipe is eliminated, so that the problem of carbon deposition can not occur.

Detailed Description
The invention is described in further detail below with reference to the following figures and detailed description:
referring to fig. 1 to 2, a steam generating system includes a boiler 1, the boiler 1 being supported by 3 support legs 1a to stand on the ground. The top of the boiler 1 is provided with an outlet 11, the periphery of the boiler 1 is provided with a fuel inlet 12, the cross section of the fuel inlet 12 is rectangular, and the fuel inlet is obliquely arranged downwards, so that the design is favorable for coal to fall into the boiler along the inlet.
A layer of bushing plate 13 is arranged below the fuel inlet 12 in the boiler 1, fuel is arranged on the bushing plate 13, and a slag outlet 15 is arranged at the bottom of the boiler. The boiler has an inlet 14 at a position below the nozzle plate 13.
The device further comprises an atomizer 2, an electrostatic dust collection device 3, a denitration device 4 and a desulfurization device 5, wherein the atomizer 2 is used for atomizing water into small droplets in the micron level, an outlet of the atomizer 2 is communicated with one end of a pipeline 21, and the other end of the pipeline 21 is communicated with an inlet 14, which is positioned below the bushing 13, of the boiler 1. The middle of the pipeline 2 is also provided with a fan 22, the fan 22 is used for supplying air, small liquid drops generated by the atomizer are sent into the boiler at an accelerated speed, and meanwhile, oxygen in the air is accelerated to pass through the boiler as soon as possible, so that the boiler burns more intensely.
An outlet 11 at the top of the boiler 1 is sequentially connected with the electrostatic dust removal equipment 3, the denitration equipment 4 and the desulfurization equipment 5. The electrostatic dust removing equipment is used for removing smoke dust particles in water vapor, and the electrostatic equipment is selected to mainly reduce the pressure loss of the steam. The water vapor after the dust removal firstly passes through the denitration equipment, the denitration equipment needs high-temperature conditions, and the water vapor after the dust removal is still very high in temperature, so that the operation of the denitration equipment can be met. The secondary desulfurization equipment has no requirement on temperature, so that the secondary desulfurization equipment can be placed behind the denitration equipment for treatment.
When the device is used, the atomizer atomizes water into micron-level small droplets, the micron-level small droplets enter the boiler along with air, then the small droplets are heated by the fuel layer along with ascending air flow from the lower part of the bushing plate to form high-temperature water vapor, and then the high-temperature water vapor flows out from an outlet at the upper part. The temperature of the steam at the outlet is kept at about 350 ℃, if the temperature is too low, the air quantity of the fan is reduced, otherwise, the air quantity of the fan is increased. According to the device, water is directly contacted with fuel, so that heat loss does not exist, a heat exchanger is not needed for collecting the waste heat of the flue gas, and the cost is greatly reduced. And a water pipe is eliminated, so that the problem of carbon deposition can not occur.
