This article explores whether ammonia is a reliable fuel for heat and electricity generation in domestic applications. First, the combustion characteristics, including adiabatic flame temperature, ignition delay time, laminar speed are analysed compared with conventional fuels such as natural gas, dimethyl ether, hydrogen, syngas, under 12 kWe turbine 45kWth boiler conditions. Furthermore, of a...

Cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. Among the equipment used in cement industries, boilers are one of the energy-consuming equipment. Boilers are among the common heating equipment in industrial, commercial, and institutional facilities. In this paper, the performance of thermal oil bo...

SPIN is a tool for the simulation and veriication of protocols. PROMELA, its source language, is a formal description technique like SDL and Estelle that is based on communicating state machines. The tool and the language are in the public domain and therefore widely used. The "Steam-Boiler Control Speciication Problem" consists of an informal speciication of a steam boiler system in a nuclear ...

A solution to the inverse heat transfer problem (IHP) occurring in steam pipelines is presented paper. The transient temperature at pipeline inlet was determined from measured outlet. Temporary changes of turbine are set by manufacturer and result conditions safe starting maintaining high durability its components. boiler start-up should be carried out so that time-temperature outlet equal usin...

Abstract – The main objective of the combustion controller in a thermal power plant is to regulate fuel and air in proper ratio to maintain the desired steam pressure at the turbine inlet, irrespective of the changes in steam demand. To achieve a continuous supply of steam at the desired pressure conditions is difficult to cope with inherent time delay, nonlinearity due to uncertainty of the co...

The design and operations of energy systems are key issues for matching energy supply and consumption. Several optimization methods based on the mixed integer linear programming (MILP) have been developed for this purpose. However, due to uncertainty of some parameters like market conditions and resource availability, analyzing only one optimal solution with mono objective function is not su ci...

Since 1999, DuPont has been applying the Six Sigma problem-solving methodology to a broad array of business, technical, transactional, and process problems across the corporation. One benefit of this culture change has been the way that business units approach energy efficiency. The structured Six Sigma approach, with its strong focus on statistics and data and a proven method for controlling i...

This paper evaluates the thermodynamical, economical and environmental characteristics of a cogeneration system composed of a gas turbine and a waste heat boiler (System A). Two other systems for increasing power generating efficiency are also evaluated, namely systems B and C, which are constructed by incorporating a regenerative cycle and a dual fluid cycle, respectively, into Systen A. It ha...
