Boiler with adjustable heating area

Abstract

The invention provides a boiler with the adjustable heating area. The boiler comprises a hearth, a fire grate, a water collection barrel and a steam pocket. A water cooling wall is arranged in the hearth, the water cooling wall is connected with the water collection barrel and the steam pocket, at least two sets of water cooling adjusting walls are arranged in the hearth in the height direction, each set of water cooling adjusting walls comprise four to six water cooling adjusting walls surrounding the inner wall of the hearth and in matched connection with a reserved port. The heating area ofthe water cooling wall in the boiler can be adjusted, and the efficiency is improved.

Description

technical field [0001] The invention relates to boiler combustion, in particular to a boiler with an adjustable heating area, which can adjust the heating area of ​​a 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 probl...

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
