Steam generator with water volume not exceeding 30 L

Abstract

The technical scheme of the invention discloses a steam generator with the water volume not exceeding 30 L. The steam generator comprises a pressure bearing coil pipe, a burner, a steam-water separator and a water injecting pump, wherein the pressure bearing coil pipe is a combination of an upper multi-layer mosquito-repellent incense-shaped coil pipe and a lower spiral coil pipe and is formed by synchronously winding a plurality of steel pipes, and the plurality of steel pipes have an integrated common inlet and an integrated common outlet; the water injecting pump communicates with the common inlet; the common outlet communicates with the steam-water separator; and the burner is arranged below the lower spiral coil pipe of the pressure bearing coil pipe. The steam generator has the beneficial effects as follows: the water volume does not exceed 30 L, the pipe pass is too short, the steam generator is energy-saving, environment-friendly, light as a whole, high in heat efficiency, good in safety and long in service life and generates steam rapidly, the steam output can be up to 1,000 kg / h, and the key problem that the maximum running water volume does not exceed 30 L when the steam output is 1,000 kg / h or below is well solved.

Description

technical field [0001] The invention belongs to the field of saturated steam separation, in particular to a steam generator with a water capacity not exceeding 30L. Background technique [0002] The steam generator is a thermal energy conversion device that heats the water flowing in the tube into steam and quickly outputs steam to the outside; the steam boiler in the boiler is also a device that produces steam, and the steam generator described here is a form of once-through steam boiler . As the amount of steam increases, its volume and water capacity also increase. When the water capacity exceeds 30L, it belongs to the category of special equipment boilers that need to be included in the national quality and technical supervision and management. The water capacity of previous steam generators is much greater than 30L. Even with a steam production rate of 500kg / h, the water capacity will be above 100L. The water capacity of the shell boiler is even larger, generally more ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a steam generator suitable for a water capacity of no more than 30L, which solves the defects in the prior art of excessive water capacity, too long tube, high energy consumption, and too heavy equipment as a whole. Fast gas, high thermal efficiency, steam output up to 1000kg / h, good safety and long service life
