Description

A horizontal steam generator

Technical Field

The invention relates to the technical field of steam generators, in particular to a horizontal steam generator.

Background Art

A steam generator is a heat energy conversion device that heats the water flowing in the tube into steam and quickly outputs the steam to the outside. As the amount of steam increases, its volume and water capacity must also increase. When the water capacity exceeds 30L, it falls into the category of boilers of special equipment that need to be included in the national quality and technical supervision and management. Therefore, in order to ensure the safety of use, its water capacity is generally set within 30L, which leads to the limitation of its evaporation capacity (steam production).

At present, in the prior art, the inventors have found that traditional steam generators have certain drawbacks in use. For example, traditional heated water pipes are generally only arranged on both sides of the combustion chamber (or combustion cavity), and the heat generated by the combustion in the combustion chamber is used to heat the water pipes, and the high-temperature flue gas (or hot air) generated after heating is discharged. In order to increase the evaporation amount, it is necessary to increase the length or height of the combustion chamber, resulting in its volume and size being too large. If the flue gas temperature is too high, it is generally only used for heat recovery and cooling by a cooling water tank, but the effect is not good.
