Abstract

PROBLEM TO BE SOLVED: To provide a rice hull combustion device capable of generating electricity under utilization of combustion heat of rice hull and capable of promoting combustion of the rice hull.SOLUTION: In a rice hull combustion device, a blower 12 for blowing out air through air holes 18 below a combustion table 17, an air blowing pipe 13 and an air casing 14 are installed, a screw conveyor 3 is installed inside to be contacted with the combustion table 17 and a fuel supply device 16 provided with a rice hull hopper 4 at its upper part is installed. Further, in order to drive the screw conveyor 3, there are provided sprockets 7, 10, a chain 9 and bearings 6. Combustion heat is generated under application of this rice hull combustion device, water is heated with this combustion heat to generate steam to cause a steam turbine or a steam water wheel to be rotated. With this arrangement as above, electricity is generated with a power generator cooperated with it.

Description

This power generation method is a method for generating electricity using rice husk and wood (oga powder) as fuel.

In general, rice husks can be cooked but cannot be burned. This rice husk combustion method burns rice husk by supplying oxygen.
We investigated the patent literature, but there was no similar literature related to the present invention.

Japanese staple food is rice. Rice husks are generated from the rice cultivation. Therefore, effective utilization of rice husk is an important issue.
Rice husk is used in various places. It is used mainly for paddy rice fields (Ankyo) and as a moisture regulator in the compost production process. The present invention is a method for effectively utilizing a new rice husk by a method of generating electricity using the amount of heat generated by burning the rice husk.

  The power generation method using rice husk as fuel is based on the combustion of rice husk. Supplying oxygen is important for burning rice husk that can only be cooked. In the combustion method of the present invention, combustion is promoted by supplying chaff to the combustion table 17 and simultaneously supplying oxygen 19 to the combustion table through the air holes 18.

  The rice husks are in oversupply from the whole region. Therefore, in each region, even if the rice husk combustion apparatus of the present invention is used, if power generation using the husk is performed, an extremely effective use effect of resources can be obtained. It is also a method that can contribute to the suppression of CO2 generation associated with global environmental pollution.

  This rice husk power generation method uses a lot of rice husk. Therefore, it is desirable that rice husk power generation be performed in many areas where many rice husks can be owned. In addition, power generation using fossil fuels is growing in scale, but rice husk power generation is a relatively small-scale power generation method based on the calorific value. Therefore, it is desirable that small-scale power generation facilities are performed in more regions.

A certain amount of rice husk is stored on the combustion table by driving the rice husk combustor 27 which is the inventive device of FIG. 2, kerosene is sprinkled on the rice husk, and the portion is ignited. By sending air from the blower, air is added to the chaff and combustion starts stronger. By supplying the rice husk to the hopper 4 of the rice husk combustion device 27, continuous supply is performed, and combustion starts continuously.
Steam is continuously generated by continuously heating the superheated tube 23 containing the water pressurized by the pump 22 in advance.
By rotating the steam turbine or steam turbine using the generated steam, the interlocked generator is continuously rotated to generate electricity.

  Japan Japan has no energy resources. Therefore, rice husks with a low calorific value are valuable resources generated in large quantities every year. It also has environmentally friendly features. I think it is used in many areas.

Claims (2)

The burning of rice husks can generally be burned, but not burned. The present invention is a method for generating heat by burning rice husks.
The screw conveyor 3 is moved inside so as to be in contact with a combustion table provided with a device in which air is sent out in advance from an air hole 18 at the lower part of the combustion table 17, a blower 12, a blower pipe 13, and an air casing 14. A fuel supply device 16 provided with a shell hopper 4 is installed. Further, a rice husk combustion device having a structure such as a device sprocket 7 for driving the screw conveyor 3, a 10 chain 9 bearing 6, and the like. FIG. 2 shows a structure for producing steam by heating water using the amount of heat generated from the apparatus of claim 1.
The amount of heat is generated using the rice husk combustion apparatus of the present invention. The heat is used to heat the water and make steam. Further, by rotating the steam turbine or the steam turbine using the steam, the interlocked generator can be driven to generate electricity. In other words, a method of making electricity using the amount of heat generated by burning rice husk and wood (oga powder).
