The current economic environment and ecological considerations demand innovative solutions from the foundry, iron and steel industries. Low-cost reprocessing and recycling of waste materials are becoming more and more important due to ever tougher statutory requirements for dumping of waste materials, and the continuous increase in the cost of waste disposal. 

The technical concept of a briquetting plant for the utilization of filter dust and sludge provides for the recycling of waste materials that, until now, owing to their consistency, could not be channelled back into the cycle of melting processes. 

These materials include:

- blast furnace flue dust - filter sludge from wet cleaning plants

- mill scale - filter dust from sand regeneration and fettling shop plants

- coke breeze - filter dust from hall dust extraction plants

We offer innovative and all-in-one solutions for these materials. Through the use of suitable binding agents and appropriate additives, dust deposits are recycled into a new, easily handled charge material for the melting process. The advantage of this process can be found not only in the reduction of the iron contained in dust in the melting charge, but also in the transfer of non-usable substances to the by-product "slag" which, thanks to its characteristic, is ideal for use as a road construction material.

The best pellet stove choice for you depends on a number of factors, probably the most important being the climate zone you live in, how well your home is insulated, how large the area you want to heat is, and what you want the internal temperature set at. Stoves are arranged by heat output lower on this page to allow easy pellet stove comparison.



In warmer areas such as the southern United States, 16 btu. (British Thermal Units) per square foot of heating area is adequate in a house with good insulation. In colder areas, if your house is not well insulated, you will need as much as fifty btu. per square foot. Check the maps for an idea of the winter temperature zone for your area.

Pellet stoves, being to some extent mechanical, don't like to be run flat out all the time just as you wouldn't rev your car everywhere in low gear. It's best to choose a stove that's more than adequate for your needs and run it at a medium setting.

There are a number of clean burning central heaters on the market today, and we at Hearth.com suggest you look into models that are as efficient as possible. This will give you the most heat for your fuel, while also assuring less smoke and pollution. Most pellet, corn and coal equipment is clean by default, but hand-fired wood boilers and furnaces can run the gamut from very inefficient (less than 50%) to as high as 90% or more.

In America, people typically use the pellets as a supplemental heat, much like a wood stove.

"Some houses are set up that they can use it as their primary source of heat, but most aren't. They're just meant to be a pretty fireplace," Wiberg said. "If you look at the European application, they typically have pellet fired furnaces, or boilers, where they incorporate it into the laundry room as a central heater. They're not made to be pretty, they're made to be functional."

The appliance takes care of the rest. Because the fuel is very consistent, the lighting process is usually very quick, the fire burns very hot and clean, and the temperature is steady and consistent.

 

As a rule of thumb, a wood gasification boiler will burn roughly half as much wood as a conventional wood-fired boiler for the same amount of heat. Most manufacturers recommend some form of hot water storage to accompany wood gasification boilers (500-1,000 gallons or more) and this can add significantly to the cost of the system. Make certain you carefully study the combustion system in your proposed purchase since EPA clean burning rules DO NOT apply to Central Heating. This means it is still legal to purchase and install a “smoke dragon” in many areas of the US and Canada.
