Embodiment Construction

[0019] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. The subsequent description of the specification is a preferred implementation mode for implementing the present application, but the description is for the purpose of illustrating the general principles of the present application, and is not intended to limit the scope of the present application. The scope of protection of the present application should be defined by the appended claims.

[0020] The invention provides a low-nitrogen combustion method for biomass fuel. The combustion process includes fuel entering the main combustion zone for combustion to generate...

Abstract

The invention discloses a biomass fuel low-nitrogen combustion method, and relates to the technical field of biomass fuel combustion. The biomass fuel low-nitrogen combustion method disclosed in the invention comprises the steps that fuel is combusted in a main combustion area; primary air used for fuel combustion is introduced into the main combustion area; and circulating flue gas I is introduced into the main combustion area, and the circulating flue gas I is part of flue gas output by fuel combustion. According to the method, the biomass fuel is completely combusted, and the emission of nitrogen oxides is small.

Description

technical field [0001] The invention belongs to the technical field of biomass fuel combustion, and in particular relates to a low-nitrogen combustion method of biomass fuel. Background technique [0002] Hot blast stoves are widely used in drying operations such as grain, and coal is the main fuel. The problem of non-compliance with environmental protection emission standards is common. There are also companies that install environmental protection facilities in order to meet environmental protection emission requirements and bear greater economic pressure. Biomass fuel has its own advantages as a renewable energy source. The fuel itself has low sulfur content and does not require desulfurization treatment after combustion. The use of scientific and reasonable low-nitrogen combustion technology can effectively control the emission of nitrogen oxides. In order to adapt to the increasingly stringent environmental protection requirements, in order to meet environmental prote...
