Ultra-low emission design principles

Ultra-low emission design principles

Design principles: We recommend that ultra-low emissions of small and medium-sized coal-fired boilers should be purchased as much as possible with high fuel value, low sulfur, and low ash coal, and through optimization of design to improve monomer efficiency, comprehensive utilization and other means to achieve ultra-low emission requirements . When designing an ultra-low emission system, there are the following principles: Principles for collaborative removal: In addition to removing the old three samples of major air pollutants (smoke, sulfur dioxide, nitrogen oxides), the three small samples (trioxide Sulfur, mercury and arsenic). The principle of System Optimization: Considering on the technical route, everything is for the purpose of achieving the final emission requirements. The redundancy of design parameters should not be removed, nor can it be a simple stacking of various equipment. The configuration level should be optimized to achieve "value engineering". The principle of unified integration: build an "environmentally friendly island behind the furnace" system, centralized layout, unified control, saving manpower and material resources. Single-advanced principle: every equipment technology in the system is advanced and reliable, stable operation, and emphasis on technological innovation. ENERGY SAVING AND EMISSION REDUCTION: In the selection of technical routes, we must adapt to local conditions, reduce investment and reduce costs, both to reduce emissions and save energy.
