One facility in four we visted recently had an operational-reliabilty risk involving the air-conditioning system supplying the MIS server room. the equipment supplying cooling to your data center requires the same level of quility, reliability, instrumentation control, and redundancy as the unit supplying the plant-oprations manager's or voice president's office. Appreciate have a reliablelife of 10 years.

Optimum performance of a steam-heat-exchanger process requires a certain set of design conditions, equipment in good working order, and proper ambient conditions. Both steam pressure and steam temperature need to be measured and controlled. Generally, problematic issues can be identified through brief analysis of a system by a specialist.

Strategic Planning for Energy and the Environment | Year: 2011

How much does your facility spend annually for purchased energy and utility equipment operations-$4 million, $8 million, $16 million? Would reducing those costs by 5% or 10% interest you? This article offers proven ideas for engineering personnel to optimize energy usage and utility costs in these challenging economic times of limited resources and frozen budgets.

Mill engineering and maintenance later replaced the orifice plates in the recirculation lines with robust orifice pipe nozzles. The boiler plant returned to single feedwater pump operation with no subsequent troubles. Earlier, a single pump was fully loaded due to the eroded orifice plate. They went from two pumps consuming 148 hp to one consuming 65 hp, saving approximately $100 per day in electrical power. If your low-pressure or medium-pressure boiler plant has experienced a puzzling feed pump performance issue, be sure to include the minimum flow recirculation line in your problem analysis critique. Get some advice from a utilities guru if needed; there are several experts on Google.

The article focuses on steam showers, examining how operations can be improved and waste and energy costs can be reduced. Process reviews at numerous mills over several years have indicated that many machines have ongoing operational challenges with steam shower performance. Steam shower designers have a unique challenge to develop and provide a robust system and controls that will cause condensation heat transfer to occur on the sheet for a wide range of changing operating conditions. Machine conditions can change significantly and can include basis weight changes, type of carrier felt and condition of the felt or fabric, machine speed, white water temperature and sheet viscosity and sheet temperature and consistency. Machine tenders monitor sheet profile to eliminate streaks that can cause problems in converting. However, when process operational issues arise, it is often difficult for the operating crews to identify whether the steam shower is part of the process anomaly.

Steam plant experiences indicate that two out of three units are in need of some operational improvements. Normally, 80 percent of the operating cost of a gas- or oil-fired steam plant is fuel consumption; labor, depreciation, maintenance and water treatment account for the rest. The Department of Energy (DOE) and the American Boiler Manufacturers Association (ABMA) report that there are more than 200,000 fire tube boilers and 25,000 water tube boilers currently in service in the US. A small 350-horsepower fire tube unit can consume nearly $700,000 of fuel per year. A boiler technician may spend one or two hours per day in the steam plant conducting routine water tests, collecting data and doing minor maintenance checks. Most mechanical utility systems in industry are not equipped with artificial intelligence that the computer industry is experiencing.

The article focuses on how to optimize the use of steam in the drying sections of the Yankee dryer tissue manufacturing process. Energy usage can represent as much as 50 percent of the cost of tissue manufacture. While gas-fired hot-air combustion loops are also used for drying, gas heating efficiency is generally lower than steam. Steam is produced in boilers that are 80 to 85 percent efficient as compared to direct-fired gas heating at 96 percent efficiency. The key to optimizing steam usage and drying-related energy cost is heat-transfer inside the Yankee cylinder. Condensing the steam produces an enormous energy transfer. Conditions need to be exact for this to happen most effectively, amidst all of the other process operating parameters that must be met. The closed-loop steam recirculation concept is used to maintain accurate internal cylinder pressure conditions, to effectively evacuate the condensate and reduce steam consumption.

Deaerators are large, insulated tank-car-shaped pressure vessels, which produces preheated boiler feedwater to ensure efficient steam-plant operation. It provides many benefits to a steam-plant system, including serving as a surge collection tank for process condensate return, preheating feedwater uniformly to improve boiler efficiency and providing a location for feeding and blending chemicals and testing protocol. A deaerator chemical balance can determine the percent of condensate return from the process systems required for a boiler-system technical analysis and deaerator energy balance is developed to determine deaerator steam usage and other energy data needed for the analysis of the entire steam system. The factors considered to evaluate the operational integrity of a deaerator unit such as storage-section volume for 13 min of water, a stainless-steel sulfite chemical feed line inside the vessel storage section and semi-annual testing of unit performance/dissolved O2 without chemical feed.

Several factors that include budgets need to be considered to determine the optimum energy projects for an organization. One of the factors is electricity, which is three to five times more expensive than natural gas and expected to remain same and in some regions the price of electricity is expected to continue rising at a rate of 4 to 8 percent a year because of commercial growth. Many facilities use more thermal energy (gas and oil) than electrical energy over the course of a year, but the annual cost is much less. Some electrical projects such as replacing perfectly good lighting and smoothly running motors are time consuming and result in lower overall savings. The electrical projects will not yield a good return on investment if power cost is 4 to 6 cents and if it is 10 to 12 cents, than any type of electrical project will be effective. Tabulating in an Excel spreadsheet can be an easy method of comparing economic benefits and presenting projects to management for approval.
