Water and fire direct heat exchange household heating stove

Abstract

The invention relates to a boiler, in particular to a water and fire direct heat exchange household heating stove. The technical problems that a traditional boiler is complex in structure, water scale can be generated easily, and heat exchange efficiency is not high are solved. The water and fire direct heat exchange household heating stove comprises a water tank provided with a water outlet and a water returning port, a combustor and a heat exchange cylinder arranged on the top of the water tank, wherein the top end of the heat exchange cylinder is provided with an opening. The combustor is connected with a fire outlet pipe stretching into the heat exchange cylinder. The position, close to the top end opening, of the heat exchange cylinder is provided with a water channel provided with a smoke exhaust port and a spraying port, and the bottom of the heat exchange cylinder is communicated with the water tank. The water tank guides water to the position above the water channel through a circulating pipe connected with a water pump in series. According to the water and fire direct heat exchange household heating stove, the metal intermediate medium heat exchange technology is directly replaced with water and fire direct heat exchange, and therefore the structure is simpler and more reasonable, heat exchange is more direct and faster, and efficiency is higher.

Description

technical field [0001] The invention relates to a boiler, in particular to a domestic heating boiler with direct water-fire heat exchange. Background technique [0002] Traditional household hot water boilers generally use metal media to separate water and fire, and the heat conduction between water and fire must be realized through metal media. Such a heat transfer method is not only complicated in structure and difficult to manufacture, but more importantly, due to The water temperature must be heated to 60 to 70 degrees. Under such conditions, the water in the metal pipe will inevitably form scale, and then adhere tightly to the metal pipe. As the scale increases, the thermal efficiency of the boiler will inevitably decrease. Therefore, The scale in the metal pipe must be treated, which not only increases the operating cost but also greatly reduces the service life of the boiler. Therefore, people hope to develop a water-fire direct heat exchange domestic heating boiler ...
