Whether the output of hot water, steam or thermal oil, and regardless of using coal, oil, gas, biomass or power boiler, has the following "four", namely boiler waterwall tubes, superheater tubes, reheater tubes and economizer tubes. It covers all four pipes of the boiler heating surface, the internal pressure of the working fluid bear, may be external to bear the high temperature, harsh environment corrosion and wear, excessive reconcile between water and fire, where the energy is concentrated is passed .

The biomass power plant boilers burn Sugarcane bagasse，Rice husk ,rice straw，Coconut shell，Palm kernel shell ,agricultural waste，Wood pellet or chips，Sawdust and other biomass fuels to generate steam and heat to meet different heat supply and electricity requirement.And it is widely use in large scale central heating, thermal power plant.

The Advanced Bio CFB technology further improves the well-known benefits of CFB technology's superior fuel flexibility, inherently low emissions, and high availability. Today, the Advanced Bio CFB technology offers efficient sub-critical boilers up to 600 MWe for 100 % biomass firing. This technology also offers supercritical steam parameters for biomass and coal co-firing applications up to 800 MWe. This is the result of continuous development work, building on experience and data from over 400 CFB reference boilers.

Cade Shopping Mall is located in central Shanghai Hongkou District, Shanghai Daily larger flow of people in the region. The introduction of Shanghai air pollutant emission standards, boiler flue gas emissions of nitrogen oxide emissions to less than 80 mg / m, Shopping Mall a coal-fired boilers have been used for many years, NOx emissions far super to this request, the urgent need to replace more environmentally friendly low nitrogen emission boilers. Other units through the use of fast Boiler introduction and understanding, determined and fast boiler to achieve cooperation, party fast to their specific needs to recommend one condensing gas hot water boiler of a 4.2MW for heating needs of the shopping center.
