Fuel Pellets

Pellets are a specially compressed type of solid fuel, most often cylindrical in shape, which is made from waste from the agricultural or woodworking industry. The main materials for the manufacture of fuel pellets are:

Fuel pellets made from raw materials of vegetable origin, lignin is used as a binder. It is a natural polymer that is contained in any plant or raw material of plant origin, and is capable of plasticizing when pressed under high temperature. In some cases, before pressing, water treatment and regrinding are performed, everything directly depends on the type and quality of the raw material from which the granules are made.

 

Fuel pellets from coal

In contrast to the widely used wood pellets, our company produces fuel pellets from coal dust and grade D coal. The coal fuel pellets produced by us are used both for traditional boilers and as fuel for automatic boilers. At the same time, coal pellets not only retain all the positive properties of the source material - coal, but also add new ones. In particular, the ecological cleanliness of pellets is maintained through the use of only natural (natural) binders in the briquetting process. When burned, fuel pellets do not emit carbon monoxide and other compounds harmful to human health, which are often present in traditional pellets made from wood derivatives. In addition, when burning pellets, little ash is formed and there is no unpleasant odor. We produce fuel pellets from grade D coal with a low content of ash (about 6%) and sulfur (0.6%). Such fuel pellets have a high calorific value of 5500-7100 kcal/kg due to the compaction of the source material by more than 2 times. But the most important indicator of coal pellets for solid fuel boilers is a longer burning time and, accordingly, a greater heat transfer for the same volume of fuel burned compared to charcoal or wood pellets.

Our fuel pellets from Kazakh coal grade D burn much longer than biomass pellets and produce much more heat during combustion. Fuel pellets (6-8mm) from coal are the most optimal raw materials for modern solid fuel boilers, both with manual combustion control and with automatic fuel supply. It should be noted that along with pellets for modern automatic boilers, we also offer Eco-pea coal.

Eco-peas are coal grade D (5-25mm) with a low content of ash (6%) and sulfur (0.6%), for which it received the prefix "ECO". It has a high calorific value of 5500-7100 kcal/kg. Compared to fuel pellets, eco-peas have a higher temperature and burning time, have a lower consumption per unit of heated area, and also reduce the cycle time of filling the boiler hopper. Eco-peas do not sinter, which ensures the normal operation of the automatic burner without slagging and clogging. You can learn more about eco-peas on our website, in the section Eco-pea coal.

We offer fuel pellets made from grade D coal. Practically any consumer is already aware of the features of the use and distinctive characteristics of this coal. But here fuel pellets and coal briquettes from it only in recent years are in great and great demand. And this is not surprising, because the consumption of such an energy carrier is only growing, and the pellets for boilers offered by us not only retain all the positive properties of the source material, but also have their own attractive qualities:

Thanks to all the above properties, fuel pellets from coal, along with traditional coal, have become used by an increasing range of consumers. Most often, our customers purchase pellets from hard (and brown) Kazakh coal in order to use this type as a fuel for boilers, especially for boilers with automatic fuel supply, as well as in boiler rooms and mini-boiler rooms.
