Blowers application range

The peak power net can be achieved with both a blower (low pressure) and a compressor (high pressure), but the required fuel cell stack sizes are different. For the same peak P et of 86 kW, 16.3% more operating PEM cells were needed in the stack for the blower application (500 vs. 430 cells with a constant active area of 490 cm ). The blower system was able to obtain the same net power by operating just above ambient pressure at the stack and providing sufficiently higher air mass flow rates compared to that of the compressor for much of the Pnet range. [Pg.83]

Backward-Curved Blade Blowers These blowers are used when a higher discharge pressure is needed. It is used over a wide range of applications. Both the forward and backward curved blades do have much higher stresses than the radial bladed blower. [Pg.924]

Step 2. System calculations over the entire range of possible operating conditions are required. The range must cover from the air blower minimum flow point to the expander bypass point for all reasonable variations in the applicable parameters of COj/CO ratio, fresh feed rate, flue gas temperature, ambient air temperature, and so forth. [Pg.174]

Cast-iron and steel-plate pressure fans are made by the American Blower Co., Type P Buffalo Forge Co., Type P B. F. Sturtevant Co., Steel Pressure Blower. The wheels are of paddle type number of blades from 6 to 24, width narrower than other types. Casing of spiral form (see Fig. 21). The range of pressures is from 4 to 16 oz. and the application is for forges, oil furnaces, cupolas, gas producers, boosters, etc. [Pg.164]

Application of aqueous MgO-based slurry via the soot blowers should theoretically result in lower treatment rates than other modes of application. However, data suggests that dosage rates are in the same range as oil-based MgO dispersions. However, with this mode of application, inadequate dosage or poor distribution can result in an increased ash burden, thus exacerbating the problem. [Pg.249]

Our results in the 2,4,5-T study have shown that mixers of pesticide concentrates and backpack sprayers who routinely walk through the treated area receive the highest absorbed dose. Flagmen for the helicopter crews and crew supervisors absorbed lower amounts than the mixers and backpack sprayers. Aerial application crews appeared to have lower absorbed doses than backpack or mist blower crews. The absorbed dose for the crewmembers ranged from 0.001 mg/kg for the helicopter flagmen to 0.062 mgAg for the mixers of the concentrates (Lavy et al., 1980). [Pg.169]

Libich et al. (231) studied the exposure of herbicide applicators to three herbicides while using handheld spray guns or mist blowers. They reported that the mean air concentrations ranging from 1.3 to 55.2 Ag/m well below the TLV of 10 mg/m for 2,4-D and picloram (231). [Pg.142]
