Boiler thermotechnician tt100 number of fire tubes. Thermotechnician TT100 - hundreds of cubic meters of hot water. Questionnaire for ordering industrial boilers

THERMOTECHNIK TT 100- three-way steel low-temperature hot water boilers gas-tube-smoke type, equipped with a furnace operating under pressurization. The boilers are designed for the production of heating hot water with a maximum temperature of 115°C at an allowable working pressure of 0.6 MPa. Boilers are used for work only in closed systems heat supply.

Application:The preferred areas of application for boilers in St. Petersburg are large heating and ventilation systems, hot water supply systems for industrial, administrative, domestic and other facilities, providing thermal energy technological equipment productions.

Design features:

gas boilers THERMOTEHNIK TT 100 is designed as a three-pass gas-tube boiler.

The combustion chamber - the flame tube and the boiler body have cylindrical shape. The convective heating surfaces are formed by second and third pass smoke tubes located axially symmetrically around the combustion chamber. Two-, three-row layout of second-pass fire tubes ensures high intensity of heat transfer.

The front cover of the boiler can be fully opened with the burner installed in any direction. With the front door open, convenient access to the combustion chamber and smoke tubes is provided for maintenance and cleaning of the boiler. At the bottom of the lid, auxiliary guides are provided to facilitate the process of closing the door.

An inspection hatch is provided in the upper part of the boiler body to inspect the fire tubes from the side of the heat carrier.

Wide annular space and large volume of water in the boiler provide the most optimal mode of operation of the boiler in the entire range of heat output.

There is a burner plate for mounting the burner on the front door. Visual control of the flame in the combustion chamber is carried out through the viewing eye.

To evenly distribute the weight load, the boiler has a solid frame base.

Continuous highly efficient thermal insulation of the boiler consists of laminated mineral wool mats 100 mm thick. The surface of the boiler is lined with corrugated aluminum coating, providing a spectacular appearance throughout the entire service life.

To move the boiler during installation and loading and unloading operations, lifting eyes are provided on the boiler body, installed symmetrically with respect to the center of mass of the boiler.

Two- and three-row layout of smoke tubes (as well as the use of heat-resistant intensifiers in the last pass flue gases for boilers with a capacity of 1 to 2.5 MW) increases the intensity of heat transfer, and, consequently, the efficiency of the boiler.

The boilers are certified according to the GOST RF system and are approved for use by Rostekhnadzor of the Russian Federation
The warranty period, subject to the conditions of transportation, storage, installation and operation, is 36 months from the date of commissioning, but not more than 42 months from the date of shipment from the manufacturer.

The normative life of the boiler is 20 years (subject to the requirements and conditions of the installation and operation manual).

Metal hot water boiler TT100 is mainly used in such areas as:

  • large heating and ventilation systems
  • hot water industrial
  • administrative
  • utility and other facilities
  • supply solar powered scientific and technical equipment of production

Termotechnik TT 100 gas boilers are designed as a three-way gas-tube boiler.

Most users of independent control systems do not deserve to trust domestically produced equipment. Domestic equipment is considered incapable of performing the required tasks and, when choosing, all devices where the manufacturer is the Russian Federation are avoided. Gas boilers Termotekhnik do not claim serious competition with Czech, German, Italian and other European models, but in work they show themselves at a fairly high level, and their cost is much more budgetary.

The main advantages of gas boilers

The main advantage of all national products is the budget cost, easily replaceable spare parts for repairs and readiness to work in difficult conditions, which not every gas-fired imported boiler can withstand. Among the main advantages of cast iron gas boilers are:

  • Gradual decrease or increase in power
  • Pretty simple and intuitive controls
  • Hot water preparation process
  • Enhanced Security
  • Minimum heat loss
  • Low heat loss
  • simple service
  • Unit durability

Principle of operation

Boilers Termotekhnik on gas are standard devices that do not have any unique design options. A continuous supply of methane is made to the burner in the working chamber, burning and giving off thermal energy. Next to the burner there is a heat exchanger, where the temperature is transferred to the coolant. Then the heat exchanger constantly circulates through the system, so that the batteries do not cool down, while maintaining a suitable microclimate.

Computerized automation is responsible for the control process and takes readings from control sensors, depending on the incoming information that controls next steps. The operating parameters cannot be compared with world-class well-known manufacturers, but for the domestic market they are at a high enough level. A gas boiler made of cast iron is a suitable solution for creating all available heating systems for a home, since its use is attributed to connecting an already set cycle. Usually a gas boiler made of cast iron is connected to an old heating system indoors, by increasing reliability and increasing power.

Industrial low-temperature hot water boilers TERMOTECHNIK TT100 designed for use in large closed heating systems. They are also great for ventilation, providing hot water household facilities and thermal energy of various technological equipment of large manufacturers. Steel boilers TT100 are manufactured in accordance with GOST RF and have the necessary permits from Rostekhnadzor RF.

Three-way steel boilers THERMOTEHNIK ТТ100 is of smoke-fire-tube type, equipped with a pressurized furnace and used to heat heating water at a maximum overpressure of 0.6 MPa up to a maximum of 115°C. TERMOTECHNIK boilers work perfectly with both gas and liquid fuel burners. Depending on the size, their power ranges from 1,000 kW to 15,000 kW.

Both the combustion chamber (or, in other words, the "flame tube"), and the body of the TT100 steel boiler itself are in the shape of a cylinder. A two- or three-row system for placing second-pass fire tubes, as well as the use of heat-resistant intensifiers in the last pass of flue gases for boilers with a capacity of 1 to 2.5 MW, can significantly increase the intensity of heat transfer, and, consequently, the efficiency of the boiler. In addition, a significant annular space and large volumes of water in the boilers provide the optimal mode of operation of THERMOTECHNIK TT100 in its entire range of heat output.

Easy access for inspection of fire tubes from the side of the heat carrier is provided by an inspection hatch built into the upper part of the boiler. And the TT100 front cover that opens in any direction gives convenient access to both the smoke tubes and the combustion chamber for cleaning and maintenance boiler. The lower part of the lid is equipped with auxiliary guides that make it easier to close the door.

The high strength of the THERMOTEHNIK TT100, combined with the competent fastening of the flame tube and the large volume of boiler water used, guarantees its durability. In addition, the low heat density of the TT100 furnace ensures compliance with the most stringent environmental requirements, and the low hydraulic resistance of the boiler, coupled with high efficiency allow to achieve high operational efficiency of the TERMOTECHNIK boiler.
