Energy-saving boiler

Abstract

A novel energy-saving boiler, comprising a hearth (11); the hearth (11) is provided with a furnace tank (12) on the upper part; the furnace tank (12) is provided with a flue pipe (7) therein; the furnace tank (12) is filled with liquid and is provided with a hot water outlet (16) at the top; the hearth (11) is provided with a cold water tank (3) on one side, and an open truncated cone (6) therein; a closed water circulating system is formed in a chamber between an inner surface and an outer surface of the cone; the truncated cone (6) is provided with an evaporator (5) on one side; the upper bottom surface of the truncated cone (6) faces the evaporator (5), and the lower bottom surface faces a front arch (9); the furnace tank (12) is connected to a flue gas heat recovery device (14); and the flue gas heat recovery device (14) is connected to a three-tandem-tower desulphurization precipitator (15). The boiler effectively increases heat absorption area, and has the advantages of high combustion efficiency, fast temperature rise, low exhaust fume temperature, smooth flue gas flow, good comprehensive operation effect and easy maintenance.

Description

1. Technical field: [0001] The invention relates to a boiler, in particular to a novel energy-saving boiler. 2. Background technology: [0002] In the background technology, environmental protection and energy saving have become two major themes in the development of modern civilized society. The boiler is not only an important guarantee for the development of the industrial economy, but also an indispensable tool for human life, and plays a pivotal role in production and life. At the same time, boiler emissions are closely related to people's daily life environment. Therefore, continuous innovation and the development of new energy-saving boilers with high efficiency, energy saving, low emissions, and low pollution are a major event that benefits mankind and contributes to society. [0003] Coal accounts for 95.4% of my country's actual energy structure, which makes my country a coal-fired country with coal as its main energy source. In recent years, problems such as low...

Problems solved by technology

Such a design is reasonable, but in practical application, the fire spray hole is often blocked by the coking and slagging of the fire spray plate, so that the flue gas cannot flow smoothly, affecting the operation effect of the entire boiler, and the fire cannot be stopped during the heating period. Under the conditions, it is very difficult to overhaul

Traditional boilers do not make full use of the furnace temperature, and the heating area is limited
