Improved system of boiler feed water deoxidization process

Abstract

The invention relates to an improved system of a boiler feed water deoxidization process. The improved system comprises a softened water tank, a deoxygenization water pump, an economizer, a deoxygenization water tank, steam boiler equipment and steam header equipment; the softened water tank is in communication with the economizer through the deoxygenization water pump and a cold water pipeline, and the economizer is in communication with the deoxygenization water tank through a hot water pipeline; the deoxygenization water tank is in communication with steam boiler equipment through a high-pressure feed water pump and the hot water pipeline; and the steam boiler equipment is in communication with the steam header equipment through a steam pipeline, and the steam header equipment is in communication with the deoxygenization water tank through the steam pipeline. By improving the feed water deoxidization process of a boiler, the optimization effect of boiler feed water deoxidization is achieved, the boiler is protected, and meanwhile the heat energy utilization rate of the boiler is increased.

Description

technical field [0001] The invention relates to an improved system for boiler feed water deoxygenation process, which belongs to the technical field of wood-based panel production. Background technique [0002] The existing steam boilers have long-term insufficient steam evaporation, which mainly brings about the following two problems: [0003] (1) The original deaeration system used steam to heat the feed water for thermal deaeration. Due to the insufficient evaporation of the steam boiler, the deaeration temperature of the boiler feed water could not meet the requirements (≦70°C), and the oxygen corrosion of the boiler was serious. [0004] (2) The exhaust gas temperature of the steam boiler is as high as 280°C, and the boiler heat utilization rate is low. [0005] Therefore, it is of great significance to improve the deaeration process of boiler feed water to achieve the optimal effect of deaeration of boiler feed water, protect the boiler, and improve the utilization r...
