Problems solved by technology

As an attempt, there is also a practice of mixing biomass and coal in a chain furnace or a circulating fluidized bed boiler for direct combustion. However, although this method can increase the combustion temperature to a certain extent, it cannot get rid of the dependence on fossil energy and will generate a large amount of energy. SO2, NOx and soot, which pollute the environment, are still not the best solution
[0005] In addition, when the biomass burning boiler burns, because the calorific value of the biomass itself is relatively low, when the chain furnace is used to burn the biomass, the heat often generated cannot meet the heating demand, and it cannot reach the required calorific value. , resulting in technical problems of insufficient heat

Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0031] Such as Figure 1-5 As shown, an adjustable boiler includes a furnace 1, a fire grate 2, a water collecting tube 3 and a steam drum 4. A water cooling wall 5 is arranged in the furnace 1, and the water cooling wall 5 is respectively connected to the water collecting tube 3 and the steam drum 4. It is characterized in that, The water-cooled wall 5 arranged in the inner peripheral direction of the furnace 1 includes four or six thick water-cooled wall tube...

Abstract

The invention provides an adjustable boiler. The adjustable boiler comprises a hearth, a fire grate, a water collecting cylinder and a steam pocket; a water cooling wall is arranged in the hearth, andis respectively connected with the water collecting cylinder and the steam pocket; at least two sets of water cooling adjustment walls are arranged in the hearth in the height direction; and each setof water cooling adjustment walls comprises four or six water cooling adjustment walls surrounding the inner wall of the hearth and in matching connection with reserved joints. The heated area of thewater cooling wall in the adjustable boiler can be adjusted; and the efficiency is improved.

Description

technical field [0001] The invention relates to boiler combustion, in particular to an adjustable boiler, which can adjust the heating area of ​​the water cooling wall in the boiler and improve efficiency. Background technique [0002] The rapid development of industrial modernization has brought about energy shortages and environmental protection issues, which are also core issues in today's world. Protecting the environment and using non-renewable energy in a sustainable way are important topics for today's scientific and technological workers to study. As a kind of energy and power equipment, the boiler needs to consume a large amount of energy (coal, oil, gas) resources in order to obtain the steam and hot water required for production and living processes, and the flue gas discharged from the boiler seriously pollutes the environment. Therefore, improving the thermal efficiency of boilers, saving energy and reducing pollution emissions are urgent problems to be solved i...
