High-efficiency energy-saving type steam generator

Abstract

The invention discloses a high-efficiency energy-saving type steam generator. The steam generator comprises a base (1), a shell (15), an outer container (2), an inner container (3), a combustor (8) and a fire-distributing tray (4), wherein the shell (15) is fixed on the base (1); the outer container (2) and the inner container (3) are arranged in the shell (15); the combustor (8) is arranged on the shell (15); and the fire-distributing tray (4) is used for guiding flame of the combustor (8) to the periphery of the inner container (3) and is fixed at a fire inlet formed in the inner container (3). By the steam generator, the combustion efficiency can be greatly improved, and the evaporation capacity reaches 120L / h; and moreover, the heat energy generated by combusting fuels in the inner container (3) is effectively absorbed by the water in the outer container (2). The high-efficiency energy-saving type steam generator is securely and reliably used, has functions of overpressure protection and protection of the over-low water level, and can automatically operate in an unattended operation mode.

Description

technical field [0001] The invention relates to a steam generator, in particular to a high-efficiency and energy-saving steam generator, which is widely used in the fields of military logistics support, emergency rescue and disaster relief, and the like. Background technique [0002] There are following problems in existing steam generator products: [0003] (1) The external dimensions of a traditional vertical fuel steam generator with a water evaporation capacity of 60L / h are about 500×1550mm, the volume is about 75L. Its disadvantages are: the steam output is small, and the equipment takes up a lot of space. [0004] (2) The base body of the general steam generator is made of steel plate, with a total weight of about 300 kg. The heat transfer efficiency of steel is low, which causes the heat in the inner tank to transfer slowly to the water in the outer tank. [0005] (3) The vertical fuel steam generator generally adopts the way that the burner supplies oil to the i...

AI Technical Summary

Problems solved by technology

Its disadvantages are: less steam output, large space occupied by equipment

The disadvantage of this water level gauge is: there must be a special person to operate the steam generator to work normally

Once the operator is negligent, the pressure in the steam generator may exceed the normal working pressure range, damage the equipment, and even affect the personal safety of the operator
