Sitong boiler takes several breakthroughs on boiler design, such as membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber.
Air required for Dry Bagasse Combustion. The simplest way of measuring combustion efficiency is to determine the percentage of carbon dioxide, oxygen and carbon monoxide in the, flue gases. A trace of carbon monoxide indicates incomplete combustion, whilst the carbon dioxide indicates of complete combustion [ 9 ].
Performance of Wet and Dry Bagasse Combustion in Energy lost from boiler occurs through varies sources, including, incomplete combustion, unburnt bagasse, surface radiation, convection, and energy lost by ash.

6.It optimizes bagasse burning and improves clean emission. 7.It saves bagasse due to improvement in boiler efficiency or alternatively more power can be exported to grid. 8.Dry bagasse ensures a faster response to load and maintains boiler pressure/temperature stable. 9.It generates high temperature inside boiler furnace and improves efficiency.
The thermodynamic analysis of sugarcane bagasse boilers is not a common practice in Brazil. Although the process of bagasse combustion represents most important sources of irreversibilities, this subject has not received sufficient attention because saving bagasse is not yet a top priority in the Brazilian sugar industry.

Wet cellulose, which is the principal component of bagasse, ignites more easily than dry cellulose. The Queensland University of Technology is leading a project addressing the spontaneous combustion of bagasse, which is a fundamental problem of safely storing bagasse (sugar cane fibre residue) in large stockpiles.
Sugar production is an energy intensive industry and requires both steam as well as electricity. Bagasse is the leftover of the sugarcane after crushing and it can be utilized as a fuel after burning in the boiler of sugar mill or electricity can be generated by using Organic Renkine cycle.
Jan 01, 2010 · Combustion of low-moisture bagasse facilitates constant boiler heat control. Bagasse is commonly dispersed onto combustion grates to maintain constant furnace temperature and water pressure. Operators either mechanically or pneumatically spread bagasse across the boiler grate in spreader-stoker furnaces. This action speeds drying and promotes rapid combustion. Continuous-feed bagasse boilers require dry, moisture-controlled bagasse.
