Case Study 1: Fire Damage CHP-Container Biogas Valve Gas Valve Gas Valve Bio gas Operator closed the wrong Biogas Valve Biogas still escaped overnight from Hole in the Pipe Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 17/29
Case Study 1: Fire Damage CHP-Container Province-specified fire-protection regulations were not paid attention to Technical inadequateness: - exhaust pipe did not keep the required distance (to the timber flooring and to the cables) - exhaust pipe was not insulated against the timber flooring - biogas pipe below the container was not covered with soil The operator did not detect the reason Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 18/29
Case Study 1: Fire Damage CHP-Container Conclusion: The damage has been categorized as extensive. The CHP-container has not been set up according to the actual regulations (province-specified fire- protection regulations are valid) No concerns have been expressed by the CHP provider Will the insurance pay the damage costs?

Case Study 2: Overfilling of Hydrolysis Tank Krieg & Fischer received an E-Mail from the insurance company: Damage of a concrete Tank Which Tank was not noticeable from the Documentation of the Insurance Company Insurance Company asked for an Examination of the Documentation available on site the Biogas Plant Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 20/29
Case Study 2: Overfilling of Hydrolysis Tank Data were only rudimental No Documentation No Flow-Sheet Site Layout was taken from Permission Documents and obsolete because the concrete tank was erected 2 years later The new tank was not registered by the insurance company.

Case Study 2: Overfilling of Hydrolysis Tank The screw pump was not equipped with a pressure sensor on the pressure side of the pump or a protection against dry running. The pump could only be stopped manually. Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 24/29
Case Study 2: Overfilling of Hydrolysis Tank If the maximum filling level of the tank is reached a warning massage is sent to the cell phone of the operator. He switches off the pump manually. Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 25/29
Case Study 2: Overfilling of Hydrolysis Tank At the day of the accident the operator forgot his cell phone. The pump continued pumping manure into the tank Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 26/29
Case Study 2: Overfilling of Hydrolysis Tank until the cover of the hydrolysis tank had been pushed up by the fluid pressure and blasted from the tank. Krieg & Fischer Ingenieure GmbH Speaker: Torsten Fischer March 10, 2010 27/29
Case Study 2: Overfilling of Hydrolysis Tank No documentation of the plant No process flow sheet Hydrolysis tank had been enhanced and equipped with a cover by the operator no structural calculation of the tank no safety-regulated documentation Will the insurance company pay for a damaged tank they do not know about?

Nepal Biogas Plant -- Construction Manual Construction Manual for GGC 2047 Model Biogas Plant Biogas Support Programme (BSP) P.O. Box No.: 1966, Kathmandu, Nepal September, 1994 Sundar Bajgain Programme Manager Biogas Support Programme Tel. 5521742, 5534035 Email snvbsp@wlink.com.np Introduction The success or failure of any biogas plant mainly .
biogas produced is used as energy in cooking food and heating water. The entire biogas system works normally and operates properly. But, after one year, the only problem we met is that the biogas production is low. The purpose of our study is to check if the weakness of the biogas volume is due to the dimensions of the biogas system.
the biogas plant begin to produce biogas normally you should add raw fermentation materials into the biogas plant regularly. 2) For the 1.2m3 biogas plant to keep a 0.6m3/d biogas production, 20kg cow dung or 15kg pig dung is needed daily. 3) In the period of normal operation you can increase the concentration of the
biogas technology and the construction of biogas plants was launched in Cameroon. . hands-on manual. The tables and engineering drawings contained herein provide standard values . 10 m³ biogas plant produces 1.5-2 m³ and 1001 digested-slurry fertilizer per day on dung from 3-5 head of cattle or 8 - 12 pigs. With that much biogas, a 6 - 8 .
biogas technology specifically, the government has organized the National Project on Biogas Development nation-wide, and several NGO's have been active in implementing the program on the ground. Currently, there are thought to be about 2.5 million (Dutta et al., 2007) household and community biogas plants installed around India. 1.2 Why biogas?
against, motor vehicle accidents, overexertion and poisoning.2 Many accidents involving adults happen when a person is distracted, tired, stressed or under the influence of drugs or alcohol. The best way to avoid accidents is to choose a healthy lifestyle. To be safety conscious means you're aware of being safe and preventing danger. Knowing
In some countries, biogas contributes significantly to the national energy balance. It may be used both as a fuel and to generate electricity. To produce these statistics, biogas data collection should focus on plant capacity and production of biogas and electricity. Project and policy monitoring More detailed biogas statistics may be required to
