Published online Designing, Fabrication, Performance Evaluation and Implementation of Solar-Biomass Hybrid Tunnel Dryer for Commercial Scale Drying of Several Types of Agricultural Products

Abstract

A hybrid type solar tunnel dryer is designed and fabricated for the commercial scale drying of different fruits and vegetables. A biomass burner box along with heat exchanger is used as backup heat source, which ensure continuous drying process during night and unfavorable weather conditions. Unidirectional forced convection is developed with a volumetric flow rate of 0.11m3/s, by using two DC exhaust fans installed at both sides of the drying chamber. A DC blower is used to push the hot air with a volumetric flow rate of 0.02m3/s, generated in either biomass burner or additional solar collector. The ultraviolet rays are blocked by covering the drying chamber by UV treated transparent polyethylene sheet, it also protect the product from birds, insects, dust, wind and rain. An additional solar collector ensure the attaining of suitable drying temperature inside the drying chamber. A PV system is installed which fulfills the power requirements, makes this solar tunnel dryer new and smart.The solar tunnel dryer is installed at US - Pakistan Center for Advanced Studies in Energy located in Peshawar, latitude and longitude of 34.0151° N, 71.5249° E. The experiments are performed on this dryer, while six solar tunnel dryers are installed at Swat to harness the great potential of different fruits.The experiments for the performance evaluation of this dryer are performed during the month of June, 2019.The performance parameters attained during experimentations are: collector efficiency is 28%, drying efficiency is 22% and drying rate is 1.46kg/hr for 50 kg of load. These parameters are in the range of international standards, indicating that this solar tunnel dryer is feasible and sustainable.

An charging Interface for Lithium ion Batteries Compatible with Current in-use UPS System

Published online An charging Interface for Lithium ion Batteries Compatible with Current in-use UPS System

Abstract

This work put forward the use of Lithium ion batteries as an energy storage medium with the existing uninterrupted power supplies, design for lead acid batteries by introducing an interface which takes care of different necessary parameters of Lithium Ion batteries is proposed. Li-ion battery has different voltage level per cell and demands more sophisticated control and safety measures as compare to Lead Acid battery. The interface will take its input from the UPS and will accordingly adjust its output for the Li-ion battery. The interface consists of a converter and a battery management system (BMS) for safe charging and discharging of Li-ion battery. A Li-ion battery pack topology is also proposed in the work, which ensures maximum energy extraction from the battery pack being used in UPS without compromising the life of battery pack and other constraints.

Abstract

In current time’s an immense proliferation occurred in the user’s density of wireless communication, not so far but in near past one channel was enough for the necessities of a single mobile user. Now even 4G technology is inadequate to deliver its clienteles a wider bandwidth, gain and fast communication. For need of high hasten communication technology alteration is under way and is switching from 4G to 5G. For multi-channel communication necessity, communicating gadgets are integrated with multiple bands having peculiarity to work on disparate frequency channels in a single device. In this projected work microstrip patch antenna is used as communicating tool and analyzed for one band and dual band communication at higher frequencies (mm-waves). Microstrip patch antenna is selected because of its simple design, low price, compactness and compatibility with circuit elements. A dual band U-shaped slotted Microstrip patch antenna with 28GHz and 38GHz operating bands is presented in this paper. The total area of antenna is substrate used in designing is Rogers RT 5880 having a dielectric constant 2.2. The antenna resulted in return loss of -32dB at 28GHz and -40dB at 38GHz. The simulated gain of proposed dual band is 6.7dB at 28GHz and 7.92dB at 38GHz.

Vol. 7, Issue 01, PP. 10-14, January 2020

Published online Improving the Mechanical Properties of Fine Soil using Marble Waste

ePub PDF

Abstract

In past many researchers used industrial waste to improve soil stabilization as low cost material and to save environment. Keeping this in mind, an attempt is made to evaluate the use of Marble Waste Powder (MWP) to stabilize the spacious clay. Marble industry is producing substantial amount of slurry with fairly good engineering characteristics. In this study, the marble waste slurry has been added to the soil to reduce the permeability of the dam cores. MWP was mixed with the soil with different varying proportions. Laboratory experiment include atterberg limits, liquid limit, hydrometer test, falling head permeability test, moisture density relation test, sieve analysis were performed on the treated and untreated soils. The result revealed that addition of 10-15% of MWP to the soil significantly improve in the density and strength and at the same time reduction in the permeability and plasticity of the stabilized soil with respect to varying moisture conditions is also very much improved.

Application of Unified Power Quality Conditioner in Grid Integration of Solar PV System

Vol. 7, Issue 01, PP. 01-09, January 2020

Published online Application of Unified Power Quality Conditioner in Grid Integration of Solar PV System

ePub PDF

Abstract

Modern power electronics has developed a great interest in grid integration of solar photovoltaics. The penetration of renewable energy resources causes problems of power quality, due to their intermittent behavior. These problems include but are not limited to reactive power flow, voltage dip or sag, over-voltage, distortions in current and voltage waveforms. Similarly, non-linear loads have been consistently increased on the consumer side. These power electronics-based equipment bring harmonics into the power system and as result demand of reactive power rises. This research aims a Unified Power Quality Conditioner for grid integration of solar PV. In the proposed technique, a part of the PV power is used for the power quality management and the rest of the power is sent back into the grid. The major constituents of PV system are; DC-DC boost converter, PV array, whereas, P &O algorithm is adopted to ensure the maximum power point operation of the PV array. The analysis and testing of the proposed approach have been successfully accomplished in MATLAB/Simulink. The results of the simulation reveal that along with the active power injection to the grid, the conditioner is capable to; pay compensation for harmonics, corrects sags and swells in voltage and also regulates the load voltage at its nominal value.
