The new model of PPT-4 heater is designed to heat water-gas-oil emulsion, oil, gas, or water.
PPT-4 heater is a tank mounted on supports and filled with intermediate coolant. A furnace is located along the tank axis, and the product coils are placed around the furnace. The burner on one side and the smoke pipe on the other are connected to the ends of the furnace. The burner is sheltered to ensure protection from precipitation and other external influences. The fuel piping and electrical equipment for connecting the heater to the automatic control system are also located in the same place.
Operating principle
Gaseous or liquid fuel is fed for combustion to a modular burner with automatic fuel/air ratio control. The combustion products, while moving through the furnace, transfer the heat to the intermediate coolant, cooled, and discharged into the atmosphere through the smoke pipe.
The heated product enters the heater coils, where it is heated by intermediate coolant and then discharged from the unit.
An expansion chamber is installed on the heater housing to compensate the increased volume of intermediate coolant during heating.
All elements of the heater structure are placed on the frame to facilitate transportation, installation, and dismantling.
Structural features
The heater is equipped with a new furnace design with effective heat exchange surfaces, which intensifies the heat transfer to the intermediate coolant from the combustion products.
The increased diameter of the furnace contributes to reduction of noise level.
Application of the new product coil allows to increase the heat transfer intensity from the intermediate coolant to the product due to the vortex flow mode, minimize hydraulic resistance, and contributes to self-cleaning of the inner surface.
New design solutions of the furnace and the coil can significantly reduce the physical specifications of the heater and fuel consumption.
A single-minded automatic burner is used for fuel combustion in the heater, providing smooth regulation of power in a wide range and combustion with minimal harmful emissions into the atmosphere.
