BORSIG manufactures reformed gas waste heat boilers for more than 50 years. We supply reformed gas waste heat boilers for gas inlet temperatures of up to 1,200°C and steam pressures of up to 160 bar (16,000 kPa) for petrochemical industry (ammonia plants, methanol plants, hydrogen plants, ethylene plants, styrene plants, MTBE plants, oxo-alcohol plants, direct reduction iron plants, coas gasification plants, gas to liquid plants, and others. Every reformed gas waste heat boiler is designed and manufactured exactly in accordance with the customer´s individual requirements. BORSIG offers two different designs: 1. Reformed gas waste heat boilers with BORSIG´s thin stiffened tube sheet design 2. Reformed gas waste heat boilers with thin flexible tube sheet design.

BORSIG supplies synthesis gas boilers for gas pressures up to 350 bar (35,000 kPa) and steam pressures up to 160 bar (16,000 kPa). They are used in the synthesis gas loop of ammonia plants. The boilers are equipped with U-tubes and can be mounted both in the vertical as well as in the horizontal positions. With both designs, the steam drum can be integrated into the boiler if requested by the customer. At the same time, a feed water pre-heater can be installed in the boiler when required.

BORSIG patented steam superheaters are suitable for steam pressures of up to 160 bar (16,000 kPa). The steam superheaters are arranged direct in line after the waste heat boilers which are connected to the secondary reformer or reformer – depending on the process. The steam superheater can be provided as two stage or one stage, horizontally or vertically arranged. The final design arrangement is determined by the process requirements. We have delivered steam superheaters for superheating saturated steam at a pressure stage of 12,500 kPa from 328 °C to 531 °C by cooling down process gas from 723 °C to 355 °C.

The LevelEx is available in sizes M16 to M63 or with NPT threads from 3/8" to 2 1/2". PFLITSCH manufactures the cable gland bodies from bright brass, galvanised nickel-plated brass and corrosion-free stainless steel. The LevelEx achieves protection class IP 66 or IP 68 and corresponds to the ignition protection types flameproof enclosure "Ex-d" and increased safety "Ex-e". With its wide temperature range of -60 °C to +130 °C and approvals according to ATEX and IECEx, the LevelEx can also be used under extreme environmental conditions. For armoured cables, PFLITSCH offers the LevelEX AC. It has the same technical quality as the proven LevelEx for non-armoured cables. In addition, it convinces with additional properties. For example, it scores with an innovative design for accommodating armoured cables: Two opposing windows in the armour clamping allow the correct seating of the cable armour to be checked immediately.

Application as breather/venting safety device incorporating an explosion proof flame arrester element for installation on top of storage tanks, tank access covers or breather pipes. The breather allows the unimpeded flow of gases out to atmosphere and air into the tank/pipe thereby preventing vacuum locks whilst ensuring provision of a permanent and reliable protection against any flashback into the tank/pipe. This device is not permitted to be installed in enclosed areas. Approved for all materials of the explosion group IIB3 with a maximum experimental safe gap (MESG) ≥ 0.65 mm and a maximum operating temperature of 60 °C .

For installation into pipes to the protection of vessels and components against stable detonation of flammable liquids and gases. Tested and approved as detonation flame arrester type 4. Approved for all substances of explosion groups IIA1 to IIA with a maximum experimental safe gap (MESG) > 0.9 mm. Bi-directionally working in pipes, whereby an operating pressure of 1.2 bar abs. and an operating temperature of 60 °C must not be exceeded. All sizes are tested against “stabilized burning” and withstand this up to a max. burn time BT ≤ 30.0 min. To detect a “stabilized burning” a temperature sensor must be installed at each endangered side. Mounting is acceptable in any position, in horizontal as well as in vertical pipes.
