Problems solved by technology

[0003] In order to further reduce the exhaust gas temperature and improve boiler efficiency, other heating surfaces are generally installed behind the SZS boiler body to continue absorbing heat. However, if the user needs hot air and hot water at the same time, the above configuration cannot meet the requirements.

Abstract

The invention discloses a boiler tail combined type heating surface, and aims to provide a boiler tail combined type heating surface capable of providing hot air and hot water, the technical scheme is characterized in that the boiler tail combined type heating surface comprises a boiler body, and a discharging device is further arranged behind the boiler body; the discharging device comprises a steel pipe type energy saver connected with the boiler body, a horizontal air pre-heater connected with the steel pipe type energy saver and a steel pipe type condenser connected with the horizontal air pre-heater, a combustor is further arranged on one side of the boiler body, and the combustor is connected with the steel pipe type condenser through an underground hot air duct.

Description

technical field [0001] The invention relates to the field of boiler equipment, in particular to a combined heating surface at the tail of a boiler. Background technique [0002] With the adjustment of industrial structure in large and medium-sized cities, the transformation of old areas and the construction of industrial areas, the implementation of coal ban policies in central urban areas, and the implementation of energy-saving and emission-reduction policies such as regional centralized heating and combined heat and power generation, the proportion of small and medium-sized coal-fired boilers will drop significantly, and is now developing in the direction of large capacity, high parameters, high energy efficiency, and low emissions; coal-fired boilers will be dominated by layer-fired furnaces, that is, chain grate boilers, and are moving in the direction of large capacity and high parameters The development cannot be replaced by any other coal-fired boilers; large-capacit...
