1-10 ton small biomass boiler desulfurization and denitrification equipment

     Product Introduction of Desulfurization and Denitrification Equipment for 1~10 Ton Small Biomass Boilers:

     What desulfurization and denitrification equipment should be selected for flue gas treatment of 1~10 ton small biomass boilers? For the desulfurization and denitrification equipment of 1~10 ton small biomass boilers, there are multiple options available in the market. The following is a detailed introduction to such equipment:

     I. Main Technical Types

1. PNCR Polymer Denitrification Technology

   • Working Principle: PNCR polymer denitrification technology is a new denitrification technology specifically developed for boiler flue gas denitrification, adopting an in-furnace denitrification process. Its core involves using polymer denitrifying agents, which are injected into the high-temperature zone inside the boiler furnace through the powder spraying system of the injection module. The polymer dry denitrifying agent decomposes in this zone, fully mixes with the flue gas, and reduces nitrogen oxides in the flue gas.
   • Technical Advantages: Operating costs are significantly lower than those of SCR denitrification technology, and the flue gas denitrification efficiency is higher than that of SNCR technology.
   • Application Example: The PNCR dry denitrification equipment for 1~10 ton small biomass boilers provided by Botou Shiheng Dust Removal Equipment Co., Ltd. has prices that vary based on the order quantity. The higher the order quantity, the lower the unit price.

2. SCR and SNCR Denitrification Technologies

   • These two technologies are also common boiler denitrification technologies. SCR (Selective Catalytic Reduction) technology typically requires the use of catalysts to promote the denitrification reaction, while SNCR (Selective Non-Catalytic Reduction) technology does not require catalysts.
   • Both technologies have their advantages and disadvantages. SCR technology generally offers higher denitrification efficiency, but the investment and operating costs may also be higher. In contrast, SNCR technology is relatively simple and economical, but its denitrification efficiency may be slightly lower.
