Steam generation module

Abstract

The invention discloses a steam generation module. The steam generation module comprises a combustion chamber, a finned heat exchanger, a tube type light tube heat exchanger and a low-nitrogen fire grate burner, wherein the finned heat exchanger, the tube type light tube heat exchanger and the low-nitrogen fire grate burner are sequentially arranged in the combustion chamber from top to bottom; acold water inlet and a hot water outlet are formed in the finned heat exchanger; the tube type light tube heat exchanger is provided with a hot water inlet and a steam outlet; and the hot water outletcommunicates with the hot water inlet. The steam generation module is novel in structure, the improved tube type light tube heat exchanger is adopted to replace a traditional fin type heat exchangerto be placed in the middle layer of the combustion chamber, heat absorbed by the cold water is more sufficient, and higher-quality steam can be produced. A brand-new low-nitrogen fire grate combustoris adopted by the bottom layer of the combustion chamber, so that the heat exchange amount is improved while the generation of nitric oxide is reduced, and the steam generation module is energy-savingand environment-friendly.

Description

technical field [0001] The invention relates to the technical field of steam generating equipment, in particular to a steam generating module. Background technique [0002] Driven by the national "coal to gas" policy, gas steam engines or steam generators have been widely used in national production and life in recent years. Ordinary modular steam generating equipment consists of multiple groups (generally 1 to 4 groups) of steam generating modules, each group is independent of each other and can be used alone. Each group of steam generation modules is composed of three-stage steam unit units with similar structures connected by copper pipes, so that the heat exchangers in the three-stage steam unit units are connected to each other and connected in series to form a single channel. Taking the three-stage three-layer finned heat exchanger as an example, cold water enters from the top heat exchanger and flows through the first-stage top heat exchanger, the second-stage top he...
