Steam generator

Abstract

The invention discloses a steam generator. The steam generator comprises a steam generation assembly, a heating cylinder, a waste gas output pipe and a liquid inlet header; the heating cylinder is arranged outside the steam generation assembly in a sleeving manner, a tail gas combustion heating area is formed between the heating cylinder and the steam generation assembly, and the tail gas combustion heating area is provided with a combustion catalyst reacting with tail gas, wherein the heating cylinder is provided with a tail gas inlet and a waste gas outlet which are communicated with the tail gas combustion heating area; the waste gas output pipe is communicated with the waste gas outlet; the liquid inlet header comprises a first flange plate and a second flange plate, and the first flange plate is arranged at the bottom of the hot waste gas heating cylinder; and the second flange plate is provided with a liquid conveying inlet, the first flange plate and the second flange plate areconnected in a matched manner to form the liquid inlet header, and the liquid inlet header is communicated with a liquid conveying pipe through the liquid conveying inlet. The steam generator solves the problems that an existing steam generator generates steam through electric heating, efficiency is low, energy consumption is high, and tail gas energy is wasted are solved.

Description

technical field [0001] The invention relates to the technical field of steam boilers, in particular to a steam generator. Background technique [0002] With the rapid development of building a resource-saving and environment-friendly society, the vigorous development of circular economy, the promotion and application of renewable energy and energy-saving products have become the focus of social attention in recent years. The demand for steam is increasing year by year, and the existing steam equipment is generally an electric boiler heating system. [0003] However, the existing steam generator generates steam through electric heating with low efficiency and high energy consumption. The tail gas produced by the factory can further release heat with the combustion catalyst, and the tail gas in the factory is directly discharged, resulting in waste of tail gas energy. Contents of the invention [0004] Therefore, the embodiment of the present invention provides a steam gene...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the embodiment of the present invention provides a steam generator, which effectively solves the problems of low efficiency, high energy consumption and waste of exhaust energy in existing steam generators that use electric heating to generate steam, and the tiny liquid inlet chamber formed by setting flanges satisfies the requirements of the steam generator. At the same time, the size of the steam generating device can be reduced as much as possible to reduce the occupied area. In addition, its capacity can be reduced, its capacity pressure can be reduced, and the number of regular inspections can be reduced.
