industrial boiler cases coal fired boiler biomass
In the worst case, coal could be mixed into fuel to help combustion of wet biomass.In order to reduce corrosion caused by Chloridion Cl which is rich in biomass fuel, special steel is applied on industrial boiler cases coal fired boiler biomass HT and LT area. Industrial package Boiler is designed tomatch a 4.5MW condensing steamturbine, or suitable backpressure steamturbine as per steam consumption of factory.
In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water industrial boiler cases coal fired boiler biomass to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
WNS type industrial boiler cases coal fired boiler biomass and gas boiler SZS What's the difference? After the state has increased in recent years, efforts to manage the environment, improve air quality, all walks of life are generally boiler retrofit or replacement gas boiler became a coal-fired boiler, the implementation of coal to gas boilers in large-scale, often encounter some customers when purchasing gas boiler, except consulting WNS type boiler and gas SZS type gas boiler, which both thermal efficiency higher? Now, I give you a brief overview about the difference between the two.
Major effects of fuel on industrial boiler cases coal fired boiler biomass design
1.A wide range of coal properties can lead to over-sized pulverizing/firingequipmentwhich will in turn lead to a limitation on turn down and a possible increase in auxiliarypower consumption. This will also increase the furnace size and the SH and RH will need to be sized properly, which can be difficult at times, to get the rated outlet temperature.
2.Over-sizing of pulverize-rs and air heaters to handle occasionally high moisture coals will require excessive tempering air when handling normal moisture coals. Ultimately all these will result in higher gas outlet temperature, reducing the horizontal boiler efficiency.
3.The behavior of the ash during the combustion process and managing the coal-ash are the major issues in horizontal industrial boiler design. Deposition and slagging, heat transfer upsets, and fouling in convection passages are some of the major issues to be dealt during operation of the boiler.
