How much steam produce with 1kg coal fuel?

posted:2016-06-06

Chain grate boiler are widely used by some industry and countries, especially in Pakistan. Usually, they often use coal fuel to heating coal fired boilers. Most of our clients will ask a question how much steam produce with 1kg coal fuel before they buy chain grate boiler. Today, we will talking about this questions briefly.H2NIndustrial Steam Boiler

Second, we should consider how to calculate the true cost of steam:H2NIndustrial Steam Boiler

Knowing the correct cost of steam is an important for many reasons, and all of them have to do with improving the company’s bottom line, including: H2NIndustrial Steam Boiler
• To properly evaluate the economics of proposed process efficiency or capacity-improvement projects; if the calculated cost is not accurate, many good energy projects may be missed or rejected, and bad projects may be approved for implementation H2NIndustrial Steam Boiler
• To serve as a basis for optimizing the steam generation system, and minimize costs H2NIndustrial Steam Boiler
•To ensure more effective negotiations with the utility or third party Independent Power Producers H2NIndustrial Steam Boiler
•To properly evaluate proposed cogeneration projects. Steam is used for a variety of applications in commerce and industry: H2NIndustrial Steam Boiler
• Process heating H2NIndustrial Steam Boiler
• Vacuum jets H2NIndustrial Steam Boiler
• Shaft work for mechanical drives H2NIndustrial Steam Boiler
• Power generation H2NIndustrial Steam Boiler
• Space heating. H2NIndustrial Steam Boiler

In industrial manufacturing facilities, process heating accounts for an average of more than 60% of thermal energy use, predominantly in the form of steam. Process heating also accounts for a significant portion of controllable operating costs. It is one of the few areas of opportunity where management can reduce operating costs and improve profits.H2NIndustrial Steam Boiler

The True Cost of SteamH2NIndustrial Steam Boiler

In most companies, the reported cost of steam is the average cost of generation at a particular production rate. The total operating costs—fuel, power, water, chemical additives, labor, maintenance, depreciation, interest, and administrative overheads—are divided by the total amount of steam produced. This may be a convenient corporate financial benchmark, but is not particularly useful for managing the steam system to minimize costs. For that, we need a better method for steam cost accounting.H2NIndustrial Steam Boiler

One of the problems is that the cost of steam depends on the generation rate, especially in complex multi-boiler multi-fuel plants that also have steam turbines. To most people, this is not intuitively obvious. In this BestPractices Steam Technical Brief, we will show how to calculate the steam cost at different process operating rates, and demonstrate through an illustrative example that the only way to do this accurately is through steam-system modeling.

Accurately determining steam costs is important for monitoring and managing energy use in a plant, for evaluating proposed design changes to the generation/distribution infrastructure and the process itself, and for continuing to identify competitive advantages through plant efficiency improvements. Steam costs are highly dependent on the path that steam follows in the generation and distribution system. Simulation models are simple, convenient, and reliable tools to follow these paths, calculate the correct costs, and to optimize the system. The method used for evaluating utility costs has a dramatic effect on project economics, and therefore the investment decision. Improper utility pricing can lead to bad decisions; good projects can be discarded, and bad projects can be implemented. Regrettably, this is relatively common. To avoid such mistakes, it is imperative that plant engineers and managers use appropriate methods for steam pricing, taking into account all the parameters that impact energy costs—fuel, condensate, power generation, and cooling water—when evaluating proposed projects.H2NIndustrial Steam Boiler
