Embodiment Construction

[0023] exist figure 1 In the process, the waste is burned in the incinerator system (1), and the high-temperature flue gas produced enters the waste incineration boiler for waste heat recovery, and high-quality steam is generated and sent to the steam turbine generator set. A high-temperature and high-pressure (9.8MPa, 540°C) waste incineration boiler has a horizontal suspension structure. A channel (5), a connecting flue (21) and a second channel ( 6), three channels (7) and horizontal channels (8). The water-cooled combustion chamber (4) is composed of a membrane-type water-cooled wall around the grate, refractory bricks are laid in the contact area with the garbage, and high thermal conductivity silicon carbide castables are laid in the rest of the area to reduce the temperature of the combustion chamber to avoid coking. The flue gas recirculation and secondary air nozzles (23) are arranged in the front and rear arch areas of the water-cooled combustion chamber (4). When t...

Abstract

The invention relates to the field of urban household waste incineration, in particular to a high-temperature and high-pressure garbage incineration horizontal boiler. The main steam pressure of the garbage incineration horizontal boiler is 9.8 MPa, and the main steam temperature of the garbage incineration boiler is 540 DEG C. The garbage incineration horizontal boiler is of a horizontal suspending structure, and a water cooling combustion chamber is adopted. A first channel, a first and second channel connecting channel, a second channel, a third channel and a horizontal channel are sequentially arranged in the flue gas flowing direction. A screen type overheater is arranged at the upper portion of the second channel, a special high-heat-conduction plastic material is laid at the outer portion of the screen type overheater. An evaporation protector I is arranged at the lower portion of the third channel. An evaporation protector II, a high-temperature overheater, an intermediate-temperature overheater, a low-temperature overheater and an economizer are sequentially arranged in the horizontal channel. The heat efficiency of a matched garbage incineration power plant steam turbinegenerator set system can be increased to 34%.

Description

[0001] Technical field [0002] The invention relates to the field of municipal solid waste incineration, in particular to a horizontal waste incineration boiler with a main steam temperature of 540° C. and a main steam pressure of 9.8 MPa. Background technique [0003] At present, domestic and foreign waste incineration power plants mostly use boiler steam at 4mPa and 400°C. Due to the low initial steam parameters, the thermal efficiency of the whole plant is generally lower than that of conventional fuel power plants. At present, there are three ways to improve the thermal efficiency of waste incineration power generation: increasing the initial steam pressure, increasing the steam temperature, and intermediate reheating. Among them, increasing the steam temperature and pressure is the most ideal and effective technical means. However, since domestic waste contains elements such as Cl, S, and alkali metals, after increasing the steam temperature and pressure, the superheater...
