Vertical Steam Vaporizers

Vertical Steam VaporizersAlternate Energy Systems offers a line of shell-and-tube vaporizers that can be configured for steam-heating, or for circulating hot-water. Capacities for both versions range from 200 gph to over 10000 gph (400 kg/h to over 20000 kg/h). The outer shell of these types is made from carbon steel; the inner, multi-pass tube bundle can be made from carbon steel (standard) or from stainless steel. The tube bundle and all propane piping conform to Section VIII, Division I of the latest edition of the ASME Boiler and Pressure Vessel Code. The pressure vessel carries the ASME "U" stamp and is National Board registered.

The prices shown below include dual liquid carryover protection through an ultrasonic liquid level transmitter in the pressure vessel, and through "smart" liquid carryover protection with Rosemount pressure transmitter and Rosemount temperature transmitter in the vapor outlet. If the high liquid level switch is tripped, the liquid inlet valve (solenoid valve) closes. It re-opens automatically when the liquid level is again below the high-limit. If the "smart" liquid carryover protection trips, a manual re-start is required.

Pressure gauges and thermometers in steam or water inlet and outlet, and in the pressure vessel and vapor outlet, are standard.

Vaporizer design, wiring, controls, and electrical components and their installation comply with the latest editions of NFPA #58 and NFPA #70. The wiring on the vaporizer, and all electrical components, are explosion-proof and comply with Class I, Division 1, Group D requirements.

All safety devices of the vaporizer, including the dual liquid carryover protection, are monitored by a programmable logic controller (Siemens S7-1200 or Allen-Bradley MicroLogix-1x00), which is connected to a high-resolution color LCD display with Touch Screen Operator Interface. The operator interface provides start/stop control for the vaporizer; it displays the system status, and any failure conditions that may occur, in plain English (with date/time stamp). The enclosure for the PLC and the operator interface are to be installed in a non-classified location. A small explosion-proof enclosure, installed on the vaporizer skid, provides local start/stop and alarm reset functions.

All control systems are equipped with remote monitoring and control software through a built-in VNC server (built into the operator interface). The remote-client software is included and is supplied as an open license for installation on an unlimited number of PCs or Laptops.

VSV Steam Vaporizers are equipped with electronic steam temperature control valves with pneumatic actuator, and automatic Steam Trap. Water circulation and water temperature control for VWB vaporizers is to be provided by external equipment.

Standard lead time on all models is 12 weeks. Actual lead times depend on factory workload and may vary.

Water Flow Requirements are based on 185°F (85°C) water temperature and 40°F (22°C) inlet/outlet temperature differential.
Steam Consumption is directly proportional to momentary load
(example: if vaporizer is used at 50% nominal capacity, it consumers only 50% of max. steam consumption).
Weights and dimensions are approximate. Dimensions are for heat exchanger shell only.
Trim and accessories are not included in dimensions.
Specifications are subject to change without notice. Call factory or distributor for price quotation and actual lead times.
