WWQL type gas and solid dual phase energy saving and environmental protection boiler, which has the national invention patent, has won the "national key new product" and "national industrial boiler energy saving product" title: the boiler thermal efficiency is higher than the national standard of about 6.6%, the initial dust concentration is lower than the national standard 50%. High temperature gasification chamber, fly ash carbon deposition device, high temperature furnace, combustion, carbon content is lower than the national standard, scattered coal to achieve clean combustion and energy-saving emission reduction of the dual effect. Known as "never smoke black smoke boiler".
