Description

technical field

[0001] The invention relates to the technical field of thermal equipment, in particular to a fully premixed condensing gas heat exchange equipment and a heat exchange method. Background technique

[0002] Energy is the basic material basis for a country to develop production and realize social progress. At present, my country's energy structure is still dominated by coal. The massive mining and use of coal has brought great pollution and damage to the environment. The task of adjusting the energy structure is imminent. Natural gas is the cleanest primary energy among fossil fuels, with very little impurity content and excellent environmental protection. Due to the support of national policies in recent years, the demand for gas appliances has increased year by year. Therefore, it is of great significance to improve the thermal efficiency of gas heat exchange equipment and promote the efficient utilization of gas resources in today's environment of energy sav...
