Micro-pressure high-temperature boiler

Abstract

The invention provides a micro-pressure high-temperature boiler which is further improved and perfected on the basis of the traditional low-pressure boiler. The micro-pressure high-temperature boilermainly comprises a boiler shell, a boiler bag, a smoke barrel and a built-in superheater which is respectively provided with a smoke gas channel and a steam channel, wherein the built-in superheater is assembled in the smoke barrel directly communicated with a boiler hearth so that saturated steam can efficiently exchange heat with high-temperature smoke gas in the built-in superheater and is heated and converted into high-temperature super-heat steam, the super-heat temperature is ensured to be raised to 180 DEG C to 200 DEG C on the basis of the micro-pressure safety of 0.04MPa, and the capability of carrying and transmitting heat energy of the steam is largely enhanced. The invention has the advantages of compact structure, low making cost, high heat exchange efficiency, low running expense and high safety performance, thereby being especially suitable for middle and small enterprises to install and use and has good popularization and application prospects.

Description

Technical field: [0001] The invention relates to a low-pressure steam boiler, which belongs to the technical field of boiler equipment, in particular to a micro-pressure high-temperature boiler. Background technique: [0002] As an important thermal energy equipment, the boiler occupies a very important position in the process of promoting the development of the national economy. According to relevant data, my country is already one of the countries with the largest production and use of coal-fired boilers. This is not only related to my country's rich coal resources, but also because coal-fired boilers have the obvious advantage of lower operating costs in terms of technical and economic indicators compared with oil-fired or gas-fired boilers, so that coal-fired boiler products will still occupy a dominant position in the boiler market. important position. According to the survey: In the current boiler market, there is a huge potential demand for small steam-water dual-purp...
