Biogas Production Anaerobic digestion?
Hi, A typical gas system comprises the digester cover, pressure and vacuum relief devices, water trap, flame trap, pressure regulator, gas meter, check valve, pressure gauges, waste gas burner and a gas holder. Mixing of digesters by means of gas re-circulation requires a compressor. The digester is covered to contain odours, maintain temperature, keeps air out and to collect the gas. Fixed covers are more usual than floating covers. During normal operation, there is a space for gas collection between the cover and the liquid surface of the digester contents. The cover of a digester has certain unique features that the operating staff must be aware of, for example, how the variation in pressure and the level inside the digester may affect the cover. The biggest danger associated with the operation of fixed cover digesters occurs when the pressure relief device mounted on top of the digester fails or the sludge overflow line blocks and the liquid level in the digester continues to rise. In such a situation, the excess gas pressure inside the digester can exceed the maximum design pressure and damage the cover or its mountings. Fixed covers can also be damaged by excess negative pressure (vacuum) or if the rate of waste sludge withdrawal exceeds the feed rate or the vacuum relief device fails. The function of the pressure relief device is to allow pressure that exceeds a safe level to escape from the digester. The manufacturer's specifications should provide the following information to enable the operating staff to control the gas system safely. (a) The system's normal operating pressure (mm water gauge). (b) The pressure at which the pressure relief device should operate. (c) The rated gas flow capacity of the pipes. A gas system generally comprises three pressure relief devices; one mounted on the cover of the digester, one on the gas holder and one situated at the end of the gas line before the gas burner. This device releases gas to the waste gas burner before the design gas pressure of the digester cover is reached. The vacuum relief device functions in the opposite manner to the pressure relief device and allows air to enter the digester in the event of the waste sludge being withdrawn too rapidly. Air should not, under normal conditions, be allowed to enter the digester because a mixture of air and methane is potentially highly explosive. Gas leaving the digester is almost saturated with water vapour. As the gas cools, the water vapour condenses causing problems. The problem is more severe when digesters are heated. To solve the problem it is essential to remove as much of the moisture as possible before the gas comes into contact with the gas system devices. For this reason, water traps should be located as close to the digester as possible. All piping should be sloped a minimum of 1% towards the water trap, which should be situated at a low point in the gas line. Flame traps are emergency devices installed in gas lines to prevent flames travelling back up the gas line (flashback) and reaching the digester. The flame trap generally consists of a box filled with stone or a metal grid. If a flame develops in the gas line, the temperature of the flame is reduced below the ignition point as it passes through the trap and the flame is extinguished. Pressure regulators are used when a lower pressure than the system operating pressure, is required for a specific device such as a boiler water heater or incinerator. Regulators maintain a constant gas pressure at the point of use The rate of gas production is probably the most sensitive process control indicator at the disposal of the operating staff. Gas meters should be regularly serviced so as to give accurate and reliable gas readings. Every effort should be made to have the gas meter calibrated every six months. Check valves (non-return valves) are installed in the gas line to allow gas flow in one direction only i.e. out of the digester. Gas pressure gauges indicate the pressure in the gas system and assist in locating any blockages in the line. If a blockage occurs, a pressure reading downstream will register a lower pressure than that of a gauge upstream. The pressure relief device at the waste gas burner safely flares excess gas to the atmosphere and thus reduces the potential for a dangerous accumulation of gas in the system. Many anaerobic digestion waste treatment plants have a means of storing excess gas. This can be in the form of either a floating roof on the digester or a separate gasholder. A mixture of biogas and air can be explosive. Methane gas in concentrations of between 5% and 15% in air by volume is explosive. Operating staff on waste treatment plants should ensure that no air is allowed to enter the digester or gasholder. All piping and equipment must be sealed properly to prevent gas from escaping to the outside. There must be no smoking and all electrical installations, including light switches, torches etc must be of the explosion-proof type, as the smallest spark could ignite escaped gases.

How To Make A Gas Wall Heater More Efficient?
1) The first and the most important step is to shut off the gas that is running to the heater. Most heaters have a valve between the gas line and the heater that shuts off the gas. Allow the heater to completely cool before attempting any of the following steps. 2) Remove the front of the heater, which is usually a grid made of either metal or glass. The grid is held to the heater by a pair of screws that are either along the bottom edge or the sides of the heater. As with all the parts of the heater, clean the grid before reattaching it later. 3) The main burner for the heater should be immediately behind the grid. The burner is usually a stainless steel round or oval bar that runs side-to-side inside the heater. The bar has holes in the top where the gas flames appear when the heater is turned on. Using a six-inch adjustable wrench and a pair of channel lock pliers, remove the burner from its mount inside the heater. There should be some brass grips or fittings on one side of the burner mount. After loosening them with the wrench and pliers, slide the burner out of the mount. 4) Do not slide the burner completely out of the heater, as the pipes connecting it to the gas line will break. The pilot light should not have to be removed as long as the burner is slid too far out. Take a bristled brass brush, and buff the edges of the holes and inside the holes along the burner. Next, take a vacuum cleaner and vacuum the holes as far as the hose can reach. Go over the burner very thoroughly when vacuuming, as any leftover dirt will lead to problems when reactivating the furnace. 5) Finally, place the burner back in the heater and re-slide it into the mount. Take care that the brass fittings are all fitted tightly to the burner. Take a wet cloth and wipe down the burner, the ignition assembly and the pilot light. Re-fit the grid on the front of the heater and screw it back into place.
If the spce heater flame goes out how long should you wait before trying to restart the heater?
30 minutes when the burner has cooled
Can the wind blow out the burner on the hot water heater?
A big enough gust of wind could possibly blow out pilot light, which would cause burner to go off. Unlikely burner to get blown out by wind.

Why is it safer to evaporate alcohol using an infra red heater rather than using a Bunsen burner?
The Bunsen burner uses an ope flame, making it easier for the alcohol to ignite.
