Along with the development of world economy, the people environmental protection consciousness enhancement, trade environment for the economic times has gone, instead, pay attention to the environment and economy, the human and the nature harmonious and sustainable development of economy. Thermal power plant pulverized coal furnace fuel combustion NOx pollution to the environment and the harm to human health was gradually known by people and attention in recent decades. Low NOx pulverized coal furnace is thermal power plant, the renovation of a new direction. This paper introduced the mechanism of NOx formation and to reduce NOx resulted in the development and application of the technology. Through analyzing the current situation of guangzhou power plant boiler operation, prevent slagging double dimensions, low NOx combustion technology retrofit scheme, to affect combustion in furnace two key dimensions (length scales and pulverized coal combustion furnace space) to focus on the object, the comprehensive optimization on the system, to prevent slag, burnt out, the purpose of integration of low NOx, and establish the mathematical model to analysis and prove the feasibility of retrofit scheme. Through the scheme, can greatly reduce the NOx emission of boiler, achieved the NOx emission standards prescribed by the state, and maintain its economy.
