Many refinery complexes in Texas are aging: At sites across the region, it is not uncommon to find boilers that are more than 50 years old. As a result, these facilities can be hit with costly unplanned outages as well as being subject to higher fuel costs due to inefficiency.
The LX Gas/Low NOX Series is offered with boiler models ranging from 50 to 300 hp. The industrial boilers use natural gas or propane and are available in a range of steam pressure options (300, 170 or 15 MAWP).
The 500°F (260°C) gas-fired oven is supplied with a shelf truck and equipped with shelf supports on 3.5” centers. A modulating natural gas burner provides 175,000 BTU/hr, and a 2,000-cfm, 2-hp recirculating blower motor provides horizontal airflow from a top-mounted heat chamber.
Boiler water treatment is critical to ensuring your boiler is operating as efficiently as possible, and no proper water treatment program is complete without a thorough understanding of the feedwater setup. A crucial step in preparing the feedwater for the boiler is preheating and deaerating the water in a separate vessel directly upstream of the boiler.
Feedwater tanks are heated storage tanks that do not have a specific deaerating section and operate at atmospheric pressure. In addition to being a feedwater reservoir, these tanks also act as condensate receivers, cold-water makeup locations and as a point for chemical injection.
Cross contamination in the pharmaceutical industry is not just an issue for those working in it, but for the wider public as a whole. As general awareness of the potential issues has increased, more questions are being asked of manufacturers and health professionals about the safety, integrity and potential side effects of a range of products and medicines.
Continuous drying systems can effectively dry or dehydrate many products in the process markets. When considering continuous-conveyor vs. fluid-bed or rotary industrial dryers, keep these points in mind.
The use of optical fiber for temperature sensing is expanding beyond safety applications. Optical sensors are replacing spot sampling in implementations that require accurate heat measurement and control.
The D Series offers nominal throughputs from 600 to 5000 lb/hr (272 to 2268 kg/hr). All models in the company’s large-dryer line are built around desiccant-wheel drying technology, a common touchscreen control, and a set of standard features.
When it comes to lining fired heaters in the petrochemical industry, refractory ceramic fiber has been the go-to material, but it has its drawbacks. Consider an alternative material and learn how it can mitigate refractory ceramic fiber’s limitations.
In the petrochemical world, refractory ceramic fiber (RCF) — also known as aluminosilicate wool (ASW) — has long ruled as the material for lining fired heaters. It is not hard to understand why: The material possesses several attributes that ensure it performs well in the harsh environment.
