What Is a Heat Torch?

The torch system is a special combustion facility used to handle combustible and flammable toxic gases and steam that cannot be recovered and reprocessed in petrochemical plants, oil refineries, chemical plants and other plants or devices. Important measure.

The ground flare

The ground torch system can ensure timely, safe and reliable venting and combustion when the gas needs to be discharged, and ensure low noise and smokeless combustion during operation.

The ground torch system is mainly composed of a control valve, a ground torch (composed of a burner group, a radiation protection heat shield and a protective wall), and a ground torch automatic ignition system.

The ground torch system can completely control the gas release combustion flame inside the radiation-proof heat shield, and the fire cannot be seen from the outside.

flame. Can minimize the impact of heat radiation and noise on workers and surrounding equipment

D--Minimum distance from the center of the flame to the target object, unit (m);

--transmitted thermal radiation factor; F--accepted

(1) The heat radiation diffused by the torch is small.

(2) Convenient maintenance. Except for the high closed body, the rest of the facilities are on the ground.

(3) Air pollution, light pollution and noise pollution to the surrounding [wiki] environment [/ wiki] are minimized, and the safety of the torch operation is improved.

(4) The floor space is small, because the ground torch will burn on the ground and no fire rain will occur. The fire prevention distance is mainly determined based on the radiant heat calculation.

Based on these characteristics of ground torches, in the early 1970s, foreign countries began research and development of ground torches, and developed a variety of ground torch emission systems, mainly divided into large displacement multi-stage multi-burner ground torches and closed ground torches. . Multi-stage multi-burner ground torches have been used in more than a dozen large-scale ethylene projects worldwide, some large-scale refining production and natural gas extraction projects, such as the MTBE torch in Malaysia, which was commissioned in 1991, and its emissions reached 1066 tons / hour The torch in Venezuela has a maximum emission of 810 tons per hour. Many chemical plants use closed ground torches. For example, in a chemical plant in South Korea, the maximum discharge of a single-barreled ground torch has reached 100 tons per hour.

Some domestic enterprises have adopted ground torches, such as the Shenzhen Huaan Liquefied Petroleum Gas Co., Ltd.'s tank torch was imported from Japan Marubeni, with a maximum emission of 6 tons per hour. The low-temperature acrylic tank adopts a torch designed by a domestic torch manufacturer. In recent years, domestic torch manufacturers have made major breakthroughs in technology update and technological innovation. Jiangsu Shanjun 21T / H, Henan Longrun 90T / H, PYL vapor internal spray burner, bad shape dispersion, smoke distribution is more even and reasonable. Easier to smoke and reduce particulate emissions, more environmentally friendly.

Discussion on the safety protection distance between the ground torch and the device The ground torch is technically advanced and has become an effective means for exhaust emissions from petrochemical production equipment and emergency device accidents, but how to properly set the torch and device safety The protective distance is the focus of the master plan design review.
