Comparative analysis of trigeneration solutions

Ioana Diaconescu — 2024-09-16

In this paper, three variants of trigeneration energy production systems are compared. The three variants are: decentralized system of individual power supply with heat, cold and electricity (SAICF), centralized system of heat, cold and electricity supply (SACCF) with decentralized consumer distribution and centralized heat supply system, cold and electricity (SACCF) with centralized distribution of consumers.
The comparative analysis is made according to the values of the tour/retour temperatures for the same type of cogeneration plant, which includes the specific installations of a GCC: cogeneration plants (GCI), the peak thermal once (ITV) and cold production plants, formed in the most general case from the absorption type (IFA) and compression type (IFC).

Identification of secondary energy resource from combustion gases for combustion air preheating - case study

Ioana Diaconescu — 2024-09-16

This article analysed the opportunity to implement the recovery of secondary energy resources in an industrial enterprise for the production of special building materials.
The inventory of secondary energy resources and the establishment of their characteristics and energy potential is an important step in the energy balance sheet.
The use of secondary energy resources, and in this case of flue gas, is one of the most effective ways to increase the use of energy consumed in industrial processes of this type.
In this paper, the internal recovery solution of the secondary energy resource identified in the flue gas is analysed for the regenerative preheating of the combustion air.

Quality audit

Daniela Ghelase — 2024-09-16

The audit is an essential tool for achieving the company's quality objectives. The main purpose of the audit is to evaluate the corrective actions necessary to eliminate deficiencies and the possibilities of improving the company's quality system and its products. Certification of quality systems cannot be obtained without conducting audits of these systems, in relation to international and European standards, applicable in the field.

Human resource management in quality assurance

Daniela Ghelase — 2024-09-16

Quality assurance includes all the factors involved in preventing quality problems within systematic and planned activities, which means the existence of a good quality managerial system in the field of human resources. The paper presents types of organizational structures that involve all personnel of a company in the assurance and continuous improvement of quality.

Implementation of total quality management

Daniela Ghelase — 2024-09-16

Total quality management (TQM) is a system of activities carried out with the aim of satisfying customers, increasing the power of employees while ensuring the lowest costs. The methods and techniques of total quality management must be applied throughout the organization, being equally useful for sales, financial, marketing, development, public relations services, as well as for the other sectors of the company. Total quality management is a method to save people from unnecessary efforts, involving everyone in the improvement processes; increasing work efficiency will lead to obtaining results in the shortest time.
