Your window air conditioner has a chemical smell what is it?
The most common odor problem from a window ac unit is that there is a buildup over time in the drip pan. The pan collects condensation and allows it to drain through a hole in the ac unit. Over time the pan will collect dirt and other particles, and can develop mold. With the ac unit unplugged the cover will need to be removed, and the pan scraped out and washed.
What does gas diffuser in welding mean?
If you are referring to TIG - GTAW it replaces the standard ceramic cup with a cup that contains 6 or so screens that align the gas stream so that it travels farther out before dissipating. Without out the screens the gas stream will travel just so far before tumbling and will not cover the puddle adequately. Having a diffuser allows one to extend the Tungsten further out. This enables you to reach places the standard cup won't.
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.

What are the safe working practices and procedures to be observed when working with tig or plasma arc welding equipment?
Before any work is done on the machine you must ensure that the correct risk assessments are in place and have been fully read so you're aware of the dangers that the machine possess. When working with machinery you should always ensure that you're competent to use it, do not use equipment that you're not trained to use. When using machinery always be aware of where you're emergency stop buttons are and where there are any areas in which you could be caught, entangled or trapped in moving parts. Always ensure that you remove any lose clothing or jewellery and tie back long hair. Ensure that all machine guards are put in place before using the machine. When using an automated welder, you should always ensure that you wear the correct P.P.E at all times. Always wear a long sleeve welding jacket to cover any bare skin to stop UV burns. Use a welding helmet or face shield when the arc is in process to protect your face from UV burns and your eyes from "arc eye". Wear safety glasses at all times to ensure that your eyes are protected from any particles or debris that my fly into your eyes. Before, during and after welding ensure that there are adequate welding screens around the equipment to protect others in the vicinity from the welding arc. Also if necessary use the correct fume extraction equipment to remove any unwanted fumes, this will not only protect your but others in the vicinity. On completion of any welding activity the machine must be shut down in the correct manner, to avoid any malfunctions and damage to the software. You should dispose of any waste, i.e. filler wire, materials, in the correct manner that applies with the COSHH regulations.

How much space a gallon of varnish cover?
The coverage area of a gallon of varnish can vary depending on the brand and type of varnish, as well as the application method. On average, a gallon of varnish can cover approximately 300-500 square feet per coat. It is recommended to check the product label or consult with the manufacturer for specific coverage information.
How do you add mahogany colour to clear varnish?
You can add a mohogany colored pigment to clear varnish. However, this is risky because if it is not done properly, or the pigment is not compatible with the varnish, it may not cover properly. There is also the possibility that it will peel off. The best policy is to purchase a varnish that is already mohogany colored from the manufacturer.
