Hot Water Boiler
A hot water boiler is a heat production system that meets heating and domestic water needs at low pressure, economically and safely. The boiler, which generally operates in the range of 90–110 °C, provides stable heating with its highly efficient heat transfer surfaces and large water volume. The system, which can operate with solid, liquid and gaseous fuel, is coupled to a rotary grate solid fuel system and utilizes economical fuels such as coal and biomass. It is produced from materials in accordance with TSE standards in any desired capacity.
Hot water boiler
A hot water boiler is a heat production system that meets heating and domestic water needs at low pressure, economically and safely. The water circulating in the boiler is generally heated to a temperature between 90 and 110 °C with the heat released by the combustion of the fuel and is transferred to the volumes or processes to be heated through a closed circuit. Since the water operates at values close to atmospheric pressure, the system is both safe and easy to operate.
The boiler is designed so that its heat transfer surfaces provide high efficiency; the heat of the flue gases is transferred to the water at the maximum rate, minimizing fuel consumption. Thanks to the large water volume, temperature fluctuations are reduced and stable and continuous heating is achieved.
The hot water boiler can be used with solid, liquid and gas fuel and can be produced in any desired capacity. When coupled with a rotary grate solid fuel burning system, efficiency is maximized and economical fuels such as coal and biomass can be utilized. This flexibility provides businesses with a wide range of maneuverability in fuel choice and low operating costs.
