A new type of full-tube panel high-efficiency fuel-fired gas-fired boiler

Abstract

A novel full tube panel type efficient oil and gas fired boiler comprises a radiant heat exchange membrane type water-cooled wall tube panel structure and a convection heat exchange tube bundle type tube panel structure, wherein the radiant heat exchange membrane type water-cooled wall tube panel structure comprises a front wall membrane type water-cooled wall, a rear wall membrane type water-cooled wall, a left side wall membrane type water-cooled wall and a right side wall membrane type water-cooled wall, and an O-shaped section structure is formed by the left side wall membrane type water-cooled wall, the right side wall membrane type water-cooled wall, a side wall lower header and a side wall upper header; the convection heat exchange tube bundle type tube panel structure comprises convection heat exchange tube bundles, a convection tube panel outside wall membrane type wall and a tail smoke chamber, the radiant heat exchange side wall membrane type water-cooled walls serve as inside wall membrane type walls of the convection heat exchange tube bundle type tube panel structure, and a convection flue with two sides being sealed is formed by the radiant heat exchange side wall membrane type water-cooled walls, the outside wall membrane type wall, an upper welding steel board and a lower welding steel board. The novel full tube panel type efficient oil and gas fired boiler is high in safety margin and good in heat transfer performance, makes use of modular design, and is capable of being rapidly installed and integrally assembled, short in installation period, easy and convenient to operate and maintain, and convenient to repair; the overall sealing performance of the whole boiler is good, heat loss due to radiation is reduced obviously, and heat efficiency is improved effectively.

Description

technical field [0001] The invention belongs to the technical field of water tube fuel gas boilers, and in particular relates to a novel full-tube panel type high-efficiency fuel gas boiler. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the change of energy consumption structure plays a decisive role. Existing coal-fired boilers have many problems such as high energy consumption and serious pollution. According to the "Twelfth Five-Year Plan" of my country's energy development, "it is urgent to change the mode of economic development and adjust the structure of energy consumption. By 2015, the proportion of non-fossil energy consumption in my country will increase to 11.4%, and the proportion of natural gas in primary energy consumption will increase to 7.5%. my country's natural gas consumption will experience rapid growth in the future. my country is or will soon build Central Asia, China-Myanm...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the defects and deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide a new type of full-tube panel type high-efficiency oil-fired gas boiler, which has a reasonable structure, less raw material consumption, safe and reliable long-term operation, high efficiency and energy saving, emission reduction and environmental protection , to avoid the defects of traditional pyrotechnic tube boilers that are prone to tube plate cracks and difficulty in large-scale; it also avoids the bottleneck of the complex on-site manufacturing process of the traditional A, D, O-type double drum and convection tube bundle boiler structure. Secondly, the entire The overall sealing performance of the boiler is good, the heat dissipation loss is significantly reduced, and the thermal efficiency of the boiler is effectively improved
