Energy-saving environmental-friendly boiler for thermal power generation

Abstract

The invention discloses an energy-saving environmental-friendly boiler for thermal power generation. The energy-saving environmental-friendly boiler for thermal power generation comprises a boiler shell, wherein a combustion chamber is ranged at the center of the boiler shell; a heating water cavity is formed between the combustion chamber and the boiler shell; a dust collection cavity is formed in the bottom of the boiler shell; a supporting net is arranged between the dust collection cavity and the combustion chamber; two hydraulic air cylinders are arranged at the two sides of the bottom end of the boiler shell; the output ends of the hydraulic air cylinders are connected to hydraulic rods; one ends of the hydraulic rods pass through the bottom end of the heating water cavity and are connected to fixing parts; the fixing parts are welded at the inner side of an outer cleaning ring; the inner side of the outer cleaning ring is fixedly connected to an inner cleaning ring through a supporting rod; scraping sheets are fixedly arranged at the bottom ends of the outer cleaning ring and the inner cleaning ring; and a filtering net is arranged on the top end of the combustion chamber. The energy-saving environmental-friendly boiler for thermal power generation scrapes scale bulges generated on side walls by using the scraping sheets on the cleaning rings, prevents scale from affecting the heat transfer of the boiler, improves the utilization rate of fuel and saves resources.

Description

technical field [0001] The invention relates to the technical field of thermal power generation equipment, in particular to an energy-saving and environment-friendly boiler for thermal power generation. Background technique [0002] Thermal power generation is a power generation method that uses the heat energy generated during the combustion of solid, liquid, and gaseous fuels such as coal, oil, and natural gas, and converts it into electrical energy through a power generation power plant. China is rich in coal resources. In 1990, coal production was 1.09 billion tons, of which only 12% was used for power generation. Thermal power generation still has great potential. Fuel chemical energy→steam thermal energy→mechanical energy→electrical energy, simply put, it uses fuel to generate heat, heats water, forms high-temperature and high-pressure superheated steam, drives the gas turbine to rotate, drives the generator rotor (electromagnetic field) to rotate, and the stator coil...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, boilers are generally used to burn coal, oil and other fuels, and long-term heating of water in the boiler will form thick scale on the side wall of the boiler. Due to the formation of scale, the heat transfer efficiency of the boiler will be reduced, resulting in a large number of waste of resources
