waste heat boiler

It was alleged that consulting engineers were negligent in their design of waste heating boilers.

The fume is collected, via a waste heat boiler, in a baghouse for recycle to the zinc operations.

Fluid-bed roasters, waste heat boilers, cyclones and scrubbers may also be used to treat off-gases.

Features include a No. 6 Oil firing burner, combustion chamber, waste heat boiler and quench / scrubber.

Area covered continuous digester, washing and screening plant, evaporators, lime kiln, rotary incinerators & waste heat boilers.

Existing incineration lines were replaced with new ones comprising counter-reciprocating grate incinerators, waste heat boilers and flue gas cleaning systems.

(chaudière sans combustion) "waste heat boiler" means an indirect-fired boiler that utilizes waste gases produced by the primary process to generate steam.

A unique feature is the waste heat boiler with a super heater and two reheater sections for the IP and LP stages of the turbine.

The Enefit process also incorporates fluid bed ash cooler and waste heat boiler commonly used in coal-fired boilers to convert waste heat to steam for power generation.

Due to shell and previous leaks, the waste heat boiler must be brought down for repairs and the Belco scrubber will be bypassed during the maintenance event,' it said.

Since project implementation, new measures have included the construction of a "summer steam line" allowing the facility to shut the boilers off and to run on a waste heat boiler for the summer months.

For example, Falconbridge Kidd recycles dust from the waste heat boilers and cyclones at the copper smelter back to the concentrate dryer to be recycled to the smelting furnace.

The off-gas has a high concentration of SO2, and exits via a waste heat boiler and electro-static precipitator to the sulphur gas treatment and acid plants in the zinc operations.

•Fe2O3. Roaster off-gases are treated in turn by a waste heat boiler, electrostatic precipitator and venturi scrubber before being directed to a sulphuric acid plant for recovery of sulphur dioxide.

Detailed technical and financial feasibility study for 50 MW gas turbine cogeneration facility based on 2 STIG (steam injection) LM 2500 gas turbines with supplementary-fired waste heat boilers.

It not only retains the original Shell SCGP waste heat boiler of coal characteristics of strong adaptability, and ability to scale up easily, but also absorb the advantages of the existing quench technology.

Electricity generated by the three 1.35 MW units is fed into the site's electricity ring main; heat from the exhaust gases is fed to a waste heat boiler to produce 3000 kg of steam per hour.

A significant difference between the Mount Isa copper ISASMELT plant and all the others is that it uses an Ahlstrom Fluxflow waste heat boiler to recover heat from the furnace waste gas.

At present all the machinery in the Vertical Retort has been removed except for a few components on the ground level and the waste heat boiler on the floors above, with salvaged components stored in the Horizontal Retort House.

The waste heat boiler on sublevel 3 had been reduced in size due to salvage operations in the 1980s as with the waste heat boiler on the first floor (ground level) which was also partially dismantled.

The GTCC CHP can attain very high overall thermal efficiencies in electricity production and by injecting additional fuel into the waste heat boiler it can produce high temperature steam which can be used for the usual industrial steam applications.

In the case of the demonstration plant, the problem was caused by sticky fume that formed an insulating layer on the convection tube bundles of the waste heat boilers, significantly reducing the heat transfer rates and thus the ability of the boilers to reduce the waste gas temperature.

The high heat transfer rate means that the Fluxflow boiler is relatively compact compared with conventional waste heat boilers and the rapid cooling of the waste gas limits the formation of sulfur trioxide ("SO"), which in the presence of water forms sulfuric acid that can cause corrosion of cool surfaces.
