Quick-change nozzles designed to save time
A range of quick-change connection nozzles, specifically designed to reduce time and increase the versatility of spraying applications, has been introduced by Bete
Nozzle cuts typical replacement times by 80%-90%
A product specifically designed to cut the cost and time traditionally associated with the maintenance of nozzles used for spray drying applications is available for the first time in the UK
Being fully committed to managing, monitoring and reducing the environmental impacts caused by its business, Drax already used Bete TH sprayers within its flue-gas desulphurisation plant, specifically to reduce SO2 emissions.
The nozzles transform bulk limestone slurry into droplets and bring these droplets into contact with the flue gas, with sufficient surface area to achieve the required SO2 removal.
However, although Drax is already at the forefront of reducing the environmental impact of its coal-fired generation operations, the company constantly strives to improve its environmental performance, and so the decision was made to assess increased measures to ensure regulatory compliance and to maintain the performance of the FGD with a wider range of fuels and with a lower pressure loss.

Spray nozzle solution increases efficiency
A spray nozzle system, specifically designed to save time and money by eliminating the problem of plugging, is now available from Bete Ltd., the UK arm of the US nozzle giant, Bete Fog Nozzle Inc.
After a full evaluation of the alternatives, Bete DTH absorber sprayers were recognised as the best solution.
The TH nozzles that Drax had been using previously delivered only a single direction spray.
DTH nozzles incorporate two hollow cone spray patterns, one spraying up and one down.
As a result, the sprayer reduces the pressure drop across the absorber and increases average droplet residence time, therefore increasing the effectiveness of the SO2 removal process.
The geometry of the DTH's design also produces the most uniform spray distribution possible in each cone.
Initially, Drax incorporated two rings of DTH nozzles in one of its six FGD absorber towers, with good results.
Thanks to this success, the company has already placed an order to introduce DTH sprayers in another of its towers, and ultimately all six towers will benefit from the advanced sprayer solution.
According to Les Lemmon, Mechanical Engineering Section Head at Drax Power Station, the system has proved a resounding success.
"Bete has delivered exactly what it promised, a highly efficient solution, performing to our precise specifications".
He continued: "Coupled with a first-class product, Bete has also provided good levels of support, accessibility and reliability".
"We look forward to completing the installation in all our FGD absorber towers".
