Capacitance water heater PVE-3.5 with heating capacity of 3.5 MW is designed to heat water in the collection, transportation, and well product preparation systems
Main parts of PVE-3.5
-
- vessel,
- product collectors,
- gas line,
- fuel treatment unit,
- service platforms,
- automation system.
The fuel treatment unit is adjacent to the side surface of the heater housing. This solution allows to obtain heat from the wall of the heater vessel and prevent the equipment from freezing inside the fuel treatment unit.
The equipment of the unit is located in a cabinet and represents a gas reduction line, which includes a filter with a differential pressure sensor to determine the degree of contamination and a gas pressure regulator to reduce the gas pressure to the required value.
The regulator is designed with a safety shutoff valve, which protects the gas equipment from pressure exceeding the standard value.
A pressure relief valve on the fuel gas line before the pressure regulator is used to discharge the excessive gas volume into the atmosphere in case of exceeding the allowable volume set on the pressure regulator.
Operating principle
Network water enters the unit through two inlet connectors, then it is heated by the walls of the furnace devices while passing between the baffles. It then enters the collection collectors and exits the unit.
Fuel gas enters the tank heating coil, where it is heated to a temperature of 50 °C, and is transferred to the fuel treatment unit.
The cooled combustion products are discharged from the heater furnace into the atmosphere through the smoke pipe.
