Stropuva was established in 2000 by one famous entrepreneur, Edmunds Strupaites. The research centers of this company are located in Lithuania. First of all, the company's management was engaged in the development of economical combustion technology. Soon, the first developments appeared that could be used in heating appliances.
Most people appreciated Stropuva long-burning boilers that run on solid fuels. If we consider gas appliances, then they are more dangerous and difficult to use. In turn, diesel and electrical devices are not entirely economical. There are also problems with the voltage in the network. In this case, consumers naturally prefer solid fuel boilers. For their functioning, you can use quite a lot of materials. Most often used coal or firewood. In some cases, coke and peat bog are preferred.
What does a solid fuel boiler consist of?
In the upper part, solid fuel heating boilers have an air damper that regulates the pressure inside the device. Next to it is a bit-thermal draft regulator. It, in turn, is connected to the support rod. Inside the cylinder there is a large air heating chamber. The boiler body also has an opening designed specifically for the removal of gases. A switch flap is provided at the bottom of the air heating chamber. Next is the air supply pipe.
On the front panel of the boiler there is a door for laying firewood. Behind it is an air distributor. The fuel is also located there. At the bottom of the boiler there is a special door for removing ash. The cable with the ring is designed to raise the air distributor. Under it is a hook and a coolant pipe. On the left side, the heating boilers have a sleeve for a thermometer. Also, manufacturers have provided a mechanism for the valve, which is responsible for the pressure. Near the base of the boiler there is a lever for switching the damper. It is located near the air supply pipe. With its help, you can easily make a choice between loading coal, as well as firewood.
