Modular hot water boiler house. 100 kW. 2021

Modular hot water boiler house based on BEETERM D-P-100 boiler

Modular water heating boiler house is designed for heating of non-residential industrial premises. Heating capacity is 100kW. Boiler house on the basis of pellet boiler BEETERM D-P-100.  Pellet supply to the flare burner of the boiler is made automatically from the fuel reserve hopper. The hopper volume is 10 cubic meters. The hopper is located on a monolithic slab next to the boiler room module.

Specialists of our company developed the design and performed the installation of a modular hot-water boiler house.

This boiler room module is quite typical, but we would like to emphasize several features. Firstly, the size of the modular boiler room is as small as possible for this configuration, and secondly, the fuel hopper is located outside the boiler room. As a rule, for 50-200 kW boiler houses we provide for the placement of the operating hopper right at the boiler, inside the module. In this case, we decided that it was necessary to reduce the frequency of fuel loading, and made a large external hopper, which can be loaded with pellet by forklift.

Main elements and thermal scheme of a modular boiler house.

• BEETERM D-P-100 boiler with flare burner and control controller
• WILO pumps. Three mains pumps and one for organizing the boiler circuit
• Barberi three-way thermostatic valve
• Expansion tank for 200l
• Heat accumulator without heat exchanger V=500l
• Fuel storage bunker (external) - volume 10 cubic meters
• Feed auger complete with gearmotor for feeding fuel from the hopper to the burner

The modular hot-water boiler house is built according to the following scheme:

Heat-carrier - water, with design temperature according to the heating schedule 70/50 °C. Fuel - pellet. Flue gas removal - natural draught through the chimney. Insulated chimney: galvanized / stainless steel in a lattice. Internal diameter of the pipe 230mm. Without hot water supply. To maintain the boiler inlet temperature at least 55 ° C, and to prevent condensate on the surface of the boiler, organized the boiler circuit. The boiler circuit is built with a three-way thermostatic valve and a boiler pump. In addition, in the boiler circuit an accumulator tank with a capacity of 500 liters was installed.

Circulation of the coolant in the heating system of the production facility is forced. Three WILO circulation pumps are used to supply the coolant. Filters are placed before the pumps and check valves after the pumps. The heating system is closed. To compensate for thermal expansion there is an expansion tank with a capacity of 200 liters.

Modular hot-water boiler house with dimensions of 3.5m by 2.55m. Module height - 4m. The walls are sandwich panels with 80mm thick insulation. Directly next to the boiler room module, a chimney in a crate was installed on a concrete base. The height of the chimney is 10.5 m

In order to protect the boiler house personnel, a gassing control system was installed. If the limit parameters are exceeded, a light and sound alarm is triggered.
