Burner integrated

Develop efficient thermal management using microchannel heat exchangers and an internal burner. Integrate processes and components to achieve smallest size and most efficient thermal management.

A refractory quarl is usually an integral part of forced-draft burners. Suitable design of burner and quarl can determine the flame characteristics. Long, short, pencil or even flat flames are possible. 

The recuperator can be positioned in the flue of the furnace or be integral with the burner (i.e. a recuperative burner). The separate recuperator is usually less costly. 

Although some integration has taken place where the appliance or boilermaker has assumed responsibility for the combustion system, overall, specialist manufacturers of combustion equipment who have developed products for each application such as boilers, furnaces, kilns and dryers, etc. serve the market. The burner makers have manufactured products which provide a packaged solution to the combustion requirement, looking after not just the burners and controls but also the fuel supply system, which may involve pumping, heating of the fuel, filtration and other peripheral equipment and functions. 

Packaged FT boilers are usually fired by oil or gas using integrated, forced-draft burners and are available as wet- or dry-back types. 

A forced-draft, gas-fired burner is seated at the top of the inner tube and produces a spinning cyclonic flame that reaches down to the bottom of the furnace tube. The hot combustible gases return over the boiler shell, which is provided with heat convection fins to extract more heat before the upward flowing gases exit the boiler. The furnace tube is fitted with a top and bottom, cast-steel flame retainer. These design features act to increase flue gas residency time and provide improved structural integrity to the pressure vessel. 

Inspect for slag or deposit formations and heavy sooting, noting the location and quantities found. Inspect the integrity of refractory. Inspect the burner area for evidence of flame misalignment or other localized heat problems that may cause overheating. 

Further optimization of the combustion and heat transfer process in burners can be expected within the next years. Therefore an integration of actuators for the optimal air-gas/fuel ratio may be useful. This control of the air-fuel ratio can be achieved by controlling...

The principles of fluidisation, discussed in Chapter 6, are applied in this type of dryer, shown typically in Figure 16.25. Heated air, or hot gas from a burner, is passed by way of a plenum chamber and a diffuser plate, fitted with suitable nozzles to prevent any back-flow of solids, into the fluidised bed of material, from which it passes to a dust separator. Wet material is fed continuously into the bed through a rotary valve, and this mixes immediately with the dry charge. Dry material overflows through a downcomer to an integral after-cooler. An alternative design of this type of dryer is one in which a thin bed is used. 

It was found that for a large spectrum of commercial operations, the kiln behaved as if Ty was approximately 920°F (494°C) regardless of reactor outlet temperature. This observation allowed the explicit model to be extensively used to explore the effects of some of the variables such as catalyst diSiisivity and air inlet location on kiln performance. However, the absence of fast coke in the model limited its usefulness, here leading us to develop a model which included the plume burner and fast coke. This next stage of advance was not possible without numerical integration.

The classical view is that a turbulent flame is equivalent to a distorted and wrinkled laminar flame. The turbulent flame brush is thus supposed to be an integrated picture of a rapidly fluctuating surface, and instantaneous schlieren pictures seem to support this interpretation 50). Grumer, however, has shown that schlieren snapshots of turbulent hot gas issuing from a Bunsen burner look very much like the flame pictures (34) the implication is that one sees, not the instantaneous flame surface, but the boundary of the hot gas. 

Because a complete conversion of the fuel cannot be achieved in practice within the fuel cell, the SOFC stack can be treated like a power generating burner so as to integrate it easily into a system model. The cooling of the stack depends on the excess air ratio. 

For reformate flow rates up to 400 Ndm3 min-1, the CO output was determined as < 12 ppm for simulated methanol. The reactors were operated at full load (20 kW equivalent power output) for -100 h without deactivation. In connection with the 20 kW methanol reformer, the CO output of the two final reactors was < 10 ppm for more than 2 h at a feed concentration of 1.6% carbon monoxide. Because the reformer was realized as a combination of steam reformer and catalytic burner in the plate and fin design as well, this may be regarded as an impressive demonstration of the capabilities of the integrated heat exchanger design for fuel processors in the kilowatt range. 

Start-up was effected by feeding methanol directly to the burner. The integrated reformer/burner reactor and the integrated PrOx reactor/cooler fabricated at IMM are shown in Figure 2.74. Characterization of the single devices and their assembly is still pending.
