Gas boiler PTVM-50

Boiler PTVM-50 Gas-heating boiler is designed for installation in heating boilers as the main source of heat supply for heating water from 70 ° C to 150 ° C, used in heating systems, hot water supply for industrial and household purposes. Installed at district thermal stations (RTS). The boiler is straight-flow with a U-shaped closed arrangement of heating surfaces. The boiler furnace is completely shielded by Ø60 × 3 mm pipes located with a pitch of S = 64 mm, and is equipped with six MGMG - 6 gas-gas burners installed opposite on the side walls. Convective heating surfaces are located in a convective gas duct with side walls shielded by Ø83 × 3.5 mm pipes, which are risers of convective sections made of Ø28 × 3 mm pipes. The rear wall of the convective gas duct is shielded with Ø60 × 3 mm pipes. The pipe system of the PTVM-50M boiler rests on the frame frame at an elevation of 5.14 m. The PTVM-30MS boiler has a reinforced frame, the pipe system is suspended using rods. May be produced in the following modifications: PTVM-50M-2 - natural gas fuel PTVM-50M-4 - natural gas fuel and fuel oil PTVM-50MS - natural gas fuel and fuel oil Boiler load control range 30 -100% of rated capacity. The boiler heating capacity is changed by changing the number of operating burners. The water flow through the boiler must be kept constant, when the heat load changes, the difference in water temperatures at the inlet and outlet of the boiler changes. By agreement, boilers can also be equipped with foreign and domestic gas burners of appropriate capacity (having the necessary technical characteristics, certificate of conformity and permission to use Rostekhnadzor). The burner device maintenance, description and specifications are provided in the documentation attached to the burner devices. Fuel oil boilers may be equipped with a gas-pulse cleaning device (GMO) to remove external deposits from the pipes of the convective heating surface. Lightweight coating of the boiler with a total thickness of 110 mm is attached directly to the screen pipes. Technical specifications of PTVM-30 boiler: Nominal heat capacity, MW - 35 Fuel type - gas/fuel oil Working pressure of water, MPa - 2.5 Inlet water temperature, ° С - 70 Outlet water temperature, ° С - 150 Hydraulic resistance, MPa - 0.25 Heating capacity control range relative to nominal, % - 30-100 Design boiler weight, kg - 77550 Pipe system weight, kg - 31360 Length, mm - 7980 Width, mm - 9100 Height, mm - 14534 Water flow, t/h - 370 Fuel flow, m3/h-gas/kg/h-fuel oil - 5200/4355 Mean time between failures, not less than - 5000 Average service life before decommissioning, years, not less than - 15 years or 75,000 hours of boiler efficiency,% not less than, gas/fuel oil - 92.2/89.5 Equivalent noise level in service area, DB, not more than - 80 Temperature of external (isolated) boiler heating surfaces, ° C - 45 Total aerodynamic drag, kg/m3, gas/fuel oil - 255.47/316.42 Exhaust gas temperature, ° C, gas/fuel oil - 150/270 Burner MS5001.1 With the help of the first class gas burners marathon ®, you provide the great advantages of the patented dreizler ® ARZ combustion technology. Gas combustion with practically no harmful substances due to internal circulation of ARZsuper exhaust gases. One of the leading combustion technologies with a low content of harmful substances. All wiring under the noise protection casing, no need for a separate electric cabinet. The casing also protects against dust and dirt while ensuring the quiet operation of the burner. The burners of this "MS" series belong to the Marathon model range and can operate on both liquid fuel and gas. In Marathon systems, the gas flow rate and the amount of air supplied for combustion are adjusted by pneumatic coupling.Combined MS burners in their gas part have all the features of the Marathon model: - automatic preliminary mixing of gas and air; - modulated power control; - no mechanical connection between the gas valve and the air damper; - Low-NOx versions using the ARZ-super system on the burner head to provide NOx emissions less than 60 mg/kWh; Liquid fuel combustion is carried out using a needle-type liquid fuel valve, spray nozzles and a special pressure washer integrated into the ARZ- super system. ARZ- super (internal flue gas recirculation) allows to reduce NOx emission during operation on liquid fuel to NOx values less than 150 mg/kWh. The parameters for CO2, CO and Saiga emissions meet the most stringent requirements. Burner package: • Two-unit version: fan is installed separately on the frame with vibration damper, with an electric motor and a fan wheel are housed in a steel plate housing; • The blending assembly design allows the burning of all types of combustible gas and light diesel fuel; • The two-pole ignition transformer for the burning of combustible gas or light diesel fuel; • The control of the presence of a flame using an ultraviolet sensor; • The control of gas loss or lack of air supply to combustion; • The combustion technology of gaseous fuel marathon ®: regulation of power of a torch between the minimum and maximum values is carried out smoothly besstupenchato by means of the servo of the air gate. • The digital manager of burning with the checked pluggable connections is mounted directly on a torch; • Use of the patented system of recirculation of combustion gases for the combined dreizler® ARZsuper torches; • The torch is checked industrially at the dreizler® stand; • A torch sound pressure level apprx. 80dB (A), the fan without noise suppressor apprx. 95dB (A); optional fan with noise absorber approx. 85 dB (A); in each individual case, the measurements are individual.
