13 ton oil fired boiler for wood process

As our 13 ton fired boiler for wood process engineer said, external circulating fluidized bed boiler lighting up is much easier than internal circulating fluidized bed boiler. This is because external cfb boiler adopts automatic ignition method, burning oil to start the whole boiler system at first. However, internal cfb boiler still uses manual ignition method, burning biomass pellet like wood to run the whole boiler equipment. As to boiler system cost, external cfb boiler is more expensive than internal cfb boiler.

Switching focus to biomass

The 125 ton CFB boiler for chemical in Pakistan, which entered commercial operation in 2010, is one of the world's largest CFB installations firing 100 per cent biomass. This unit routinely burns peat as well. Poland, for example, has now taken an aggressive position in providing incentives for the growth of biomass fired power projects, with an emphasis on maximizing the use of difficult-to-burn agricultural wastes. This Eastern European nation has significant sources of biomass usable for direct power generation, including 35 million tonnes per year of wood waste and 12–14 million tonnes per year of agro biomass.

2. Circulating fluidized bed (CFB)

Circulating fluidized bed combustion(CFBC) Advantages :

1. Fluidized bed can burn a variety of fuels-coal as well other non-conventional fuels like biomass, petro-coke, coal cleaning waste and wood. This bed contains only around 5 percent coal or fuel. The rest of the bed is primarily an inert material such as ash or sand. Fluidized bed boilers are capable of burning a wide range of fuels cleanly, including biomass fuels such as wood waste.

2. The Temperature in FBC is around 800-900°C compared with 1300-1500°C in pulverized coal combustion (PCC). Low Temperature helps minimize the production of NOx (nitrogen oxides). With the addition of a sorbent into the bed (mostly limestone), much of the so2 formed can be captured. The other advantages of FBC are Compactness Ability to burn low calorific values (as low as 1,800 kcal/kg) Production of ash which is less erosive. Moreover, in FBC, oil support is needed for 20-30 percent of the load versus 40-60 percent in PCC. FBC based plants also have lower capital costs compared to PCC based plants. The capital costs could be 8-15 percent lower.

Handan: Before the end of October to complete the transformation of more than 10 tons of steam gas 13 ton fired boiler for wood process burning low nitrogen

A few days ago, Handan City issued "on the deadline to complete the nitrogen oxide gas boiler governance" (the "Notice"), clear objectives, tasks nitrogen oxides governance gas boiler, expected to be completed more than 10 steam tons of gas before the end of October this year, low NOx combustion boiler reconstruction. "Notice" to the objectives and tasks of nitrogen oxide gas boiler control, time requirements, safeguard measures have been clearly defined.

First, the implementation of the transformation of ultra-low emissions

By the end of June 2020, the existing non-electrical gas steam boiler, hot water boiler, Stoker stoker furnace and completed the transformation of a low nitrogen combustion, soot, sulfur dioxide and nitrogen oxides reach 5mg / m³, 10mg / m³ , 30mg / m³, the new gas combustion boiler synchronizing means and is mounted low nitrogen meet emission standards. 20 tons of steam / hour or more gas-fired boiler installation atmospheric pollution automatic monitoring facilities, and networking with the environmental protection department, install a distributed control system (DCS system). 20 t steam / hour to be mounted gas-fired boiler exhaust gas nitrogen oxide analyzer.

Second, the phased completion of the task of transformation of governance

10 before the end 2018, to complete the combustion of the transformation Boilers nitrogen over 10 tons of steam, to complete the 1-10 tons of steam (having a steam tons and 10 tons of steam) combustion transform low nitrogen gas boiler before the end of October 2019, 2020 at the end of 6 before completing the transformation of low-nitrogen combustion gas steam boiler 1 ton. Counties (cities, districts) according to the actual situation, to be completed in advance of nitrogen oxides governance gas boiler.

Third, both subsidies and penalties

"Notice" requirement for acceptance of project management, to give appropriate subsidies comprehensive financial subsidies to control air pollution. Due to the unfinished task of governance be ordered to stop production of governance. For excessive emissions, fraud, unauthorized outage environmental protection facilities, waste-water treatment snuck issues such as rectification and punishment according to law; wrongdoing, be held criminally relevant personnel.
