IV. Vergassen Gasifier - Special Features

The GB Gasifired- Vergassen Advantage

The GB Gasifired - Vergassen has a range of special features that gives it a distinctive edge in gasifiers for thermal applications.

Dry Gas System

The GB Gasifired - Vergassen design incorporates a completely dry gas generation, handling & distribution system as scrubbing the gas with water is not necessary. Thus, there is no sticky „tar“ and tar contaminated effluents to be handled / disposed.

Hot Gas Filter System

The GB Gasifired - Vergassen incorporates a unique hot gas fine filtration system (optional), a first of its kind, which can clean hot gases (temperatures up to 600 °C). The dry gas filtration has an efficiency of over 96% for particulates over 10 micron size. It can typically produce a clean gas with less than 80 micrograms per m3 of particulate matter.

Compact foot print

The GB Gasifired - Vergassen series is an extremely compact gasifier. A typical 600 KWth system complete with reactor, gas cleaning & handling system would occupy a space of only 20ft x 20ft (Excluding fuel storage). The system design is such that the support structure and access platforms and ladders are integrated. The reactor does not require any foundation. So, only site preparation and light civil work (flat concrete flooring and approx.15 cu.ft foundation for blower) would be required.

Wide Range of Burners to suit any application

We have a wide range of burners which are specially designed for specific applications. Each type of burner is designed so as to meet the requirement of flame profile, flame temperature and other furnace characteristics. We also have in our range, fully automatic producer gas burners for use in applications such as baking ovens, POP kilns, hot air generators etc. where temperature control is critical. The automatic burners are fully loaded with safety features and interlocks to have reliable, safe and completely automated operation.

Quick Start and Shutdown

The GB Gasifired - Vergassen series has extremely quick start capability and reach 75% of its capacity with 30 minutes of cold start and 15 minutes of restart (within 12 hours of shut down). Typically the shutdown time is less than 15 minutes.

Automation

We have a range of optional automation features available. The automation system is designed so as to reduce the skill levels required of the gasifier operator, simultaneously ensuring, smooth trouble-free and uninterrupted operation of the gasifier system. Depending on the clients‘ requirement, the GB Gasifired - Vergassen‘s operations may be totally or partly automated. The automation modules include:

  • Reactor Pressurtrol: To maintain the required gas quantity and quality accurately.
  • Load synchronizer: To control and regulate gas generation to match the load requirement. This eliminates possibility of excess gas pressurization / low heat availability and also eliminates the need to flare excess gas.
  • Automated filter operation: To prevent problems such as choking and dust carry over from the filter.
