vertical type coal biomass wood fired 0 5 ton steam boiler

Wood Fired Steam Boiler can be widely used in many industrial areas such as paper industry, food industry, leather industry, power plant, etc. ZG Boiler as a leading industrial boiler manufacturer in China, supplies wood biomass fired vertical type coal biomass wood fired 0 5 ton steam boiler, you can select one according to your needs.

In this method of combustion, coal fuel is burned in a bed of hot inert, or incombustible, particles suspended by an upward flow of combustion air that is injected from the bottom of the combustor to keep the bed in a floating or “fluidized” state. The scrubbing action of the bed material on the coal fuels enhances the combustion process by stripping away the CO2 and solids residue (char) that normally forms around the coal fuels particles. This process allows oxygen to reach the combustible material more readily and increases the rate and efficiency of the combustion process. One advantage of mixing in the fluidized bed is that it allows a more compact design than in conventional water tube boiler designs. Natural gas or oil fuel can also be used as a start-up fuel to preheat the coal fired steam fluidized bed or as an auxiliary fuel when additional heat is required. Beside, the effective mixing of the bed makes fluidized bed boilers well-suited to burn solid refuse, wood waste, waste coals, and other non standard fuels. The fluidized bed combustion process provides a means for efficiently mixing fuel with air for combustion. When coal fuel is introduced to the bed, it is quickly heated above its ignition temperature, ignites, and becomes part of the burning mass. The flow of air and fuel to the dense bed is controlled so that the desired amount of heat is released to the furnace section on a continuous basis.

Biomass Based Power Generation

The potential of bagasse/co-generation in Zimbabwe is estimated to be 633 GWh, particularly from sugarcane. There is also the potential for power generation from wood waste generated from the timber industry with over 70,000 tons of biomass waste each year. In the long-term, this figure is projected to double by 2015. At most large timber mills, only a small fraction (~10%) of wood waste that is generated, is currently consumed in process steam boilers for lumber drying kilns, while the vast majority is burned in the open air or dumped. It’s estimated that at least 4 MW of power could potentially be generated from waste that is produced from large mills.

In response to national environmental policy development, improve the quality of people's living environment of the area, Guangdong Province, actively promote the boiler "coal to gas" action. Currently, Dongguan City, "from coal to gas," the work has entered a crucial stage, nearly two months, the city government, city atmosphere Office, the Municipal Development and Reform Bureau has organized a thorough inspection teams to supervise the Towns "coal to gas" work . Atmospheric do inspection personnel Lurui Quan admits: "From the inspection situation, many companies on the 'coal to gas' is still in the wait and see attitude, worried about the safety and cost issues."

As of March 25, Dongguan City, 26 companies of 37 coal-fired boilers (except coal-fired captive power plant boilers), it has been out of the 17 units, 14 companies were using natural gas. In addition, 12 companies of 20 coal-fired boilers, is expected to complete phase transformation within this year.

It is expected that in the near future, all industrial boilers transform the use of clean energy, Dongguan sky will be bluer.
