Problems solved by technology

[0002] With more and more subway constructions and more and more construction period requirements, more and more subway constructions choose to be constructed in winter. Due to environmental factors such as cold weather, winter construction needs to take heating measures, such as: using hot air robes or Heating in greenhouses, but traditional boilers are bulky and use a single fuel, which is not suitable for the characteristics of small subway sites, many turnover times, or deep foundation pits.

Abstract

The invention relates to a multi-medium fuel hot-air furnace and application thereof. The multi-medium fuel hot-air furnace comprises a body which is constituted by an inner liner and an outer liner.A ventilating system is arranged on one side of the outer liner, and an air supplying pipeline is connected to the end face of one side of the outer liner. The upper end face of the inner liner is connected with a chimney, and a feeding inlet is formed in the inner liner. A replaceable fuel injector is arranged at the feeding inlet, and a slag outlet is formed in the lower portion of the inner liner. Through arrangement of the replaceable fuel injector, the same hot-air furnace can be applicable to multiple media, and the universality of the hot-air furnace is improved.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to a multi-media fuel hot blast stove, which belongs to the field of concrete construction in winter construction of a main structure of a subway. Background technique [0002] With more and more subway constructions and more and more construction period requirements, more and more subway constructions choose to be constructed in winter. Due to environmental factors such as cold weather, winter construction needs to take heating measures, such as: using hot air robes or Greenhouses are used for heating, but traditional boilers are bulky and use a single fuel, which is not suitable for the characteristics of small subway sites, many turnover times, or deep foundation pits. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-media fuel hot blast stove and its application. A fuel injector is connected to the feed port, so that vario...
