Modular Tubular Heaters

PTB-5-40AModular Tubular Heater

The heater is equipped with three main modules: a heat exchange chamber, a heater base and a fan unit. Additionally, the heater consists of chimneys, gas coils pipes, an operating floor, a step-ladder, and fastening and installation devices. The heater is transported to location in form of separate modules and units. At the location the separate modules are connected by fasteners, pipes, power cables, and an automation system.
The heat exchange chamber is a heat-insulated metal case containing four coil sections of ribbed pipes. Fuel gas combustion products recycle in the heat exchange chamber and ensure uniform heating of crude oil emulsion (oil).
The heater base includes four combustor chambers with the fuel gas supply pipes and ignition devices, air charging ways (ducts) from the fan unit to combustion chambers and gas preparation facility.
The fan unit consists of a steel welded frame with an electric motor mounted on it and a centrifugal high-pressure fan connected by a V-belt drive. The fan unit includes an air intake and an air booster.

The PTB-5-40E Modular Tubular Heater

Basic distinctive features of the PTB-5-40E compared to the PTB-5-40A:

Electric control system using the automation microprocessor system enables functioning as part of pipe heater automatic control system;
Automation system enables to control additionally gas and air ratio ensuring better burning and gas concentration in the heat exchange chamber;
Additionally installed coils in the heat exchange combustor to heat fuel gas in wintertime.
