Field Tour Experiences on Energy Technology Installations-CLSU-AREC Initiated Projects

Background:

Prof. Angelito V. Angeles, Director of CLSU-AREC and our Professor in CPE721 has arranged a field laboratory tour with the group of four (4) MSAE studentsand eleven (11) BSAE students last January 22-23, 2010, as a requirement for thestudents respective subject under him. The formal tour itinerary was to visit theproject installation of solar-assisted irrigation system in Matayumtayum, La Paz,Tarlac, the biogas system in Tibag, Pulilan, Bulacan, AMTEC at UPLB, Los Banos,Laguna and the micro-hydro power system in Aquino, Tiaong, Quezon.

Objective:

The activity aims to provide actual technical know-how, experiences and

exposures on actual energy system ins tallation projects initiated and implemented byCLSU-AREC. Specifically, it aims to know the technical detail of the energyinstallation, its use, theory and application.

Methodology:

1. Field tour experience, first hand information gathering from the pro ject site.2. Hands-on learning from the actual project demonstration & implementation.3. Documentation, appreciation of hardware installation of different energy

systems.

Highlights of Result:

There were 3 energy system installations visited, as follows:

a. Solar energyb. Biomass energy (in terms of biogas)c. Water energy

1. Solar energy

The Small Water Impounding Support Project for Water Stress Communities(Tawi-Tawi Model) located at brgy. Matayumtayum, La Paz, Tarlac is a solar -assisted irrigation system and Activity Center funded by the National IrrigationAdministration thru the joint effort of Prof. Angelito V. Angeles of CLSU -AREC andthe Provincial Irrigation Officer, Engr. Prudencio Santos . The project aimed toprovide water for the irrigation of vegetab les that will be planted in the area throughdrip irrigation. Its location is surrounded with rice crop with at least 10 STWsinstallation near the site. No irrigation system in the area and dependent only onrain water during the wet season and pumped w ater during the dry season, asexplained by a farmer spectator.

The project consists of a concrete water tank and an activity center. The watertank has a dimension of 6 ft x 18 ft x 10 m. and water that will fill the tank will be rainwater during rainy season and ground water during dry season. The systemcomprises an open-type shed, water depository tank, water well, and the irrigationapplication component which has not yet been started at the time of our visit. Theshed has a floor dimension of about 20 x 20. The water well has a floor size of 18 x

6, which is used temporarily in pumping water for construction use (gravel/cementmixing, daily use of project workers) through a 5.5hp direct coupled water pump andtemporarily contain in drum prior to using (figure 2). The water depository tank is forimpounding pumped water from the well and precipitation water diverted from theroofing of the shed towards the tank (figure 3). The 5.5 Hp gasoline engine waterpump will be powered by a solar panel, 85 watts capacity temporarily installed at thesite to provide lighting for the workers (figure 4).

Its location is surrounded with rice crop with at least 10 STWs installationnear the site. No irrigation system in the area and dependent only on rain waterduring the wet season and pumped water during the dry season, as explained by afarmer spectator.

It was called Tawi Tawi model because when it rains, the place is surroundedwith flood and becomes like an island. A micro hydro will be constructed wherein awater current turbine will be used, a turbine which is not a high pressure type. Thistype of turbine generates power using water current.

2. Biomass Energy

The CLSU model biogas digester is a fixed dome type and has a capacity of10 m3. The project was a private contract between CLSU-ANEC and Atty. Calderonlocated at brgy. Tibag, Pulilan, Bulacan. It is implemented through the KilusangPangkalikasan ng Bulacan, Inc. (KPBI), Department of Energy (DOE) and CLSU-AREC.

The system is utilizing hog waste which is directed to a digester that isconstructed below the ground level. After some period of decomposing such waste itproduces flammable gas in a form of methane gas. Sludge shall necessary becollected from the digester from time to time.

During our visit at the project site, there were 15 heads of sow which providesource of waste for decomposition which eventually produces methane gas as theprocess progresses. The system was utilized for providing gas for householdcooking .I have observed the placing of water to the top of the digester where the

gas outlet pipe is located. This is to test for any gas leak. We also witnessed thetesting of flame produced by the biogas from a burner located several meters fromthe biogas digester. This meets the standards in the design of a biogas system . Thetypical process flow of the biogas system which was also observed in Pulilan projectis presented in figure 5.

3. Water Energy

The Micro Hydro Power Plant in Aquino, Tiaong has an installed capacity of30 kVA and having a head of 100 meters. It was designed to generate electricalpower to address lighting requirements, power pumps and charge batteries in thelocality. It was implemented through the CLSU-AREC, Office of Cong. Proceso Alcala and the Local Government Unit of Tiaong, Quezon. It was built to provide

electrification of the village and for supplementary irrigation of vegetable or cropproduction grown in the area. It has a 20-kW power generating capacity which wasinstalled from the highest location of collecting water (water intake) down the riverchannel at the base of the mountain (power house).

The power house provides shelter to the turbine which translates the kineticenergy of the flowing water into mechanical energy. A 30-kW generator wasattached to the shaft of the turbine to translate that energy into electrical energywhich can be distributed to the housing units in the village. A huge penstock of 12diameter shall direct water from the surge tank towards the turbine. The surge tankswere constructed from oil drums (figure 6).

However, the system is not yet functional since it is still under construction.Major parts that we were able to visit are the following: the forebay, surge tank,penstock and the turbine and generator assem bly.

The Micro Hydro Power Project was located at the mountainous area withrelatively steep terrain down the location of power house and about 8km drive fromthe town of Tiaong, Quezon (figure 7).

4. Other Activities

The Agricultural Machinery Testing and Evaluation Center (AMTEC) of theCollege of Engineering and Agro -Industrial Technology (CEAT) in Los Banos,Laguna was also visited by the group. AMTEC is the sole testing center ofagricultural machines and equipment in the Philippines. Machines intended forcommercialization can be evaluated using Philippine Agricultural EngineeringStandards (PAES), and manufacturers can refer to them in improving the design andfabrication of the machines. Engr. Romulo Eusebio who is the head of the testingand evaluation unit of AMTEC gave briefings on what AMTEC are doing, the actualset-up of testing equipment (e.i. pumps, tractor, engine, blower) and the equipmentused for testing and evaluation (figure 8). He discussed how they test agriculturalengines and how they establish a performance curve (i.e. head capacity curve, inputpower curve, efficiency curve) from actual tests performed. The group gathered othersample data during engine testing like torque, speed, fuel consumption, noise level

and temperature at exhaust. He also demonstrated the procedure on how theydetermine the brake horsepower of agricultural tractors using the prony -brakedynamometer. The

During the trip we had opportunity to view other energy systems along theroad such as the windpump system near the Pulilan NLEX exit , the solar panelinstallation for lighting at KM47 along NLEX in San Simon, Pampanga and the steamconveying pipes of a geothermal power plant in Bay, Laguna (figure 9).
