Description

Technical Field

[0001] The present invention relates to the technical field of tower boilers, and more specifically to a tower boiler with double flue separation and adjustable flow rate. Background Art

[0002] A tower boiler is a boiler with a tower-shaped structure, where the lower part is a furnace and the upper part is a convective flue. For large-capacity boilers (usually referring to boilers above 300 MW), the full tower type is rarely used, and only the semi-tower type is adopted, that is, the air preheater and the induced draft fan and forced draft fan are arranged on the ground at zero meters. The existing boilers mainly rely on the regulation of the coal-water ratio to change the temperature of the superheated steam, and during the regulation process, the change in the flue gas temperature at the furnace outlet causes the change in the outlet temperature of the reheated steam. In order to coordinate the relationship between the superheated steam and the reheated steam temperatures and make them have good steam temperature coupling characteristics, the commonly used temperature regulation methods currently include the swinging burner method, the reheater water spraying method, the flue gas recirculation method, and the flue gas distribution baffle method. However, for boilers with reheaters arranged in areas with strong radiation characteristics, the swinging burner can be used to adjust the temperature of the reheated steam; but for tower boilers, due to the relatively long distance between the furnace outlet and the flame center, the influence of the swinging burner on the reheater is small, and the swinging of the burner will affect the heat absorption of the furnace, further affecting the temperature of the superheated steam and deteriorating the coupling characteristics of the regulation of the superheater and the reheater. The method of spraying water into the reheater can only adjust the steam temperature when it is too high and cannot solve the problem of too low temperature, and it will also cause a reduction in the thermal efficiency of the unit. The flue gas recirculation method is only used under special requirements, such as to reduce the emission of nitrogen oxides.

[0003] Chinese Patent discloses a tower boiler with flue separation and adjustable flow rate (authorization announcement number CN102230614 B). In this patented technology, a number of flue separation screens are provided between two opposite side furnace walls of the boiler body, which correspondingly divide the interior of the boiler body into several flue gas channels, so that the superheater and the reheater of the boiler are respectively arranged in different flue gas channels; during the process of the high-temperature flue gas generated by combustion being discharged through different flue gas channels, the steam conveyed in the superheater or reheater provided in each flue gas channel is heated respectively to perform corresponding superheating or reheating treatment; adjustment baffles are respectively provided in the several flue gas channels, and by correspondingly adjusting the flow rate of the high-temperature flue gas in each flue gas channel, the temperature of the superheated steam output by the superheater and the temperature of the reheated steam output by the reheater can be adjusted respectively. Therefore, the present invention can respectively adjust the heat absorption levels of the superheater and the reheater, as well as the heat absorption levels on the left and right or front and back inside the boiler body, and has good control performance;

[0004] However, during the use of the above-mentioned tower boiler, the adjustment in the flue still adopts the traditional regulating baffle, which is not easy to adjust the flow rate of the inner air duct separated by the double flue, and there is a problem of affecting the adjustment effect of the flue gas flow rate in the flue.
