Flare systems can be classified according to: Structural Support: Self-Supporting Guy Wired Derrick Guy Wired Derrick Basis for design of flare: Specifications Analysis Gas Analysis Hydraulic & Noise Analysis Radiation & Flame Analysis Pressure Drop Exit Velocity Structural Stability. Flare Tips Flare tips are available in various solutions, both in smokeless and non-smokeless operations. Flare gas must always have a minimum heat content in btu / scf: Steam-assisted - 300 btu/scf Air-assisted - 300 btu/scf Non-assisted - 200 btu/scf Steam-assisted and non-assisted flares: 300 Btu/scf = 60 fps maximum Greater than 1, 000 btu/scf = 400 fps maximum Dispersion and toxic analysis: Dispersion is performed on vent gases or flare gas in the event of loosing the flame on the top of the flare system. Under this scenario, the analysis will exhibit the vent plume coordinates and concentrations of hydrocarbon components in the plume. Flare Design Standards and Guidelines : API 521 API 537

The process of pelletizing combines mixing of the raw material, forming the pellet and  a thermal treatment baking the soft raw pellet to hard spheres.  The raw material is rolled into a ball, then fired in furnace to sinter the particles into a hard sphere. ATE designed Burners, special shape burner blocks and commissioned complete combustion system. The Scope covers supply of burners, control valve racks, instrumentation, automation and hook-up with client’s DCS. Pelletizing Furnace Burners Specifications: Duel fuel type: Natural Gas and Mixed Gas ( BF+Coke Oven Gas) Calorific value: 1800 Kcal / Nm3. Burner Block: Refractory High Al2O3. Burner Rating : 1Mbtu / hr. to 12 Mbtu / hr.

Enclosed type bio gas flare system design features: Smokeless Capacity: 100% Destruction efficiency: 99 % Operating temperature: 800 - 1000 Deg C the process parameters shall be set at this temperature for PLC operation Retention time: > 0.30 seconds (minimum) at 800 - 1000 Deg C Gas pressure at flare inlet: 150mm WC Methane content: 30 to 60 % Automation:  PLC based control and operation, operation hook up with gas holder level transmitter or process input from client. With data logging and data transmission features

The horizontal heating position of ladle is mainly used for preheating and keeping the ladle warm, after or before changing and cleaning of the slide gate. Especially here the proper sealing of the ladle mouth is done by means of the specially designed trolley mounted vertical lid. In, horizontal preheaters the lid sizes and shape shall change as per the ladle opening. Heating stations are designed for single or various heating positions (e.g. The preheater is trolley mounted type) On request the preheater can be equipped with an additional door in the ladle cover for an oxygen purging lance. Depending on the conditions on site, the unit can be designed for travelling on rails. The movement can be effected pneumatically or electro-mechanical.

Warm up burners & control valve rack for vertical shaft lime klins.  Valve skid for operation & control of warm-up burner for vertical shaft kiln burner. This typically comprises of pressure regulating valve, solenoid valves, flow meter etc. Burner firing sequence controller with annunciation. Custom built burners for warm up of vertical shaft lime kilns. Typically, these are custom designed, to meet the process and space requirements. MOC of the main lance and the pilot burner is Inco alloy 600, to withstand high temperatures.  Fuel: Natural gas/ LPG/ Propane. Capacity : 6 Mbtu/hr.

Custom engineered burners and control system with valve skids designed to meet the customers' requirements. The main Objective is,   To improve ultimate product quality at client’s end. To meet environmental norms. To provide energy efficient solutions, by designing burners to operate on the process gas available with client. Use of diverse fuels, like Mixed gas, corexgas, BF gas, coke oven gas etc, to attain energy use objectives. Low NOx conventional burners for diverse fuels and furnace applications.   Alliance Thermal Engineers has designed and manufactured following:   Last furnace gas fired burners for iron ore rotary dryer. Capacity: 20000 Nm3 / hr. BF gas pressure: 800mm WC. Blast furnace gas fired burners for sintering furnace. Capacity: 7000 Nm3 / hr. BF gas. Pr. 700-800 mm WC. Suitable for Preheated combustion air @ 350 Deg. C.
