Steam Headers and Off-takes. Shell boilers are made for capacities up to around 27000 kg/h of steam. When loads in excess of this are required, two or more boilers are connected in parallel, with an installation of four or more boilers not being uncommon. The design of the interconnecting steam header is highly important.Learn More

5/7/2009 · High Ash Coals - A challenge to Power Plants - Optimisation of combustion in high ash coal fired boilers is of special interest due to the organic and inorganic mix up and the large amount of variation in the organics. One such experience with Indian low reactive coal in a tangential fired steam generator of 670 T/hr capacity is given here.Learn More
BMS Interface. The control scheme can easily interface with an external Burner Management System (BMS). A typical BMS sends four signals to the combustion controls: boiler trip, purge, light-off, and release-to-modulate. The boiler trip signal tells the boiler controls to close the fuel valve. The purge signal causes the boiler controls to open Learn More
Coal fired boiler generates thermal energy by burning coal, while biomass boiler is similar to coal boiler by burning biomass fuel like wood chip. These two boilers are widely used in power station, chemical, textile, printing and dyeing, energy, mining, paper making, agricultural industries, etc.Learn More
