HIGH-PERFORMANCE CT-M TYPE SOLID FUEL HEATING BOILER 900kW

CT-M type boilers for hot water production are designed and manufactured to utilize all types and forms of pulverized solid waste.

The heating boiler is designed and built to operate in accordance with the standards set by DECREE –02-1997 N.22, for energy recovery from raw and processed wood shaping waste, including:

SAWDUST, MEDIUM-DENSITY FIBERBOARD, ENAMELED PANELS, LAMINATED PANELS, MASONITE, ABS AND PVC EDGES, WOOD CHIPS, ETC.

It can also operate with liquid or gaseous fuels.

The boiler structure is entirely made of steel sheets, with a large water-cooled combustion chamber fully lined with high-quality refractory material, allowing complete combustion with very low pollutant and unburned particle levels.

Additionally, doors are provided for manual loading and regular maintenance.

The thermal generator consists of three horizontal smoke passes with flue tubes submerged in water and tube bundles at the ends; the smoke compartments have access doors.

GENERAL BOILER FEATURES
This is a modern technology generator for hot water production with three effective smoke passes, and its dimensions comply with I.S.P.E.S.L. standards.

The generator is a monoblock with flue ducts and equipped with all necessary accessories for automatic operation in accordance with current regulations.

It contains a large volume of water and an appropriate thermal inertia.

The boiler’s overall efficiency is very high, reaching 90% under optimal operating conditions.

H2O GENERATOR WITH SMOKE TUBES, TYPE CT-M
Our CT-M type hot water generators are designed to recover the heat content of flue gases from the heat distribution system.

The large combustion chamber size allows gases to remain at high temperatures long enough to ensure complete combustion.

Counterflow water circulation at higher speeds in zones with intense thermal load enables high heat exchange coefficients.

The architecture of the convective tube bundle with horizontally arranged smoke towers prevents ash deposits on heat exchange surfaces.

Ash is collected in an expansion chamber located beneath the tube bundle, where an Archimedean screw can be installed for automatic ash extraction.

The materials used in the construction are high-quality steel, and welding is performed manually by qualified personnel.

All construction phases are inspected by our internal control system. These features ensure high performance in both responsiveness and operation, guaranteeing continuous and long-lasting operation even under the most demanding conditions.
