oxygen trimming device for boiler

Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of ​​11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired oxygen trimming device for boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot water boiler (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.

Application: food processing, hospital, Garment factory

WNS gas fired hot water boiler is a horizontal fire tube hot water boiler both available for natural gas, city gas, etc.The product designation WNS gas fired hot water boiler stands for horizontal internal combustion with the rated evaporating capacity of 0.7-14MW in Chinese.

Steam oxygen trimming device for boiler model parameters of the gas boiler is the most common problem is a problem of scale, which we need to carry out cleaning and maintenance work. Gas boiler water treatment work is to prevent gas boiler fouling. However, due to improper or method of treatment for other conditions, often in some boilers have varying degrees junction scale. In order to ensure safe and economic operation of the gas boiler, for the scale to be cleared in a timely manner. Mechanical cleaning gas boiler 1. Method: When the gas boiler furnace has a loose scale and slag, after shutdown so that the cooling gas boiler, let go of boiler water, rinse with water after, to use flat shovel, wire brushes, and a motor milling descaling header. This method is relatively simple, the scale used for simple small gas boiler. However, labor-intensive, ineffective cleaning, easy to damage the boiler. 2. A gas boiler descaling pickling method: acid cleaning method using hydrochloric acid or nitric acid, most of the cleaning. Pickling solution by adding nitric acid or hydrochloric acid was added inhibitor of the corrosion inhibitor composition. This can eliminate the acid liquid boiler scale (scale except when nitrate, hydrofluoric acid to be added), and very few corrosion gas boiler. Descaling pickling has dissolved, exfoliation and slack action. 3. The cleaning gas boiler alkali cooking method: alkali cooking method cleaning descaling, pickling cleaning effect than the difference method, but since a base boiled loose scale, and therefore difficult to remove for the scale with hydrochloric acid, before acid It may be treated with a base to conduct a cooking method. Alkali cooking method is simple, relatively small side effects. The disadvantage is a long time cooking oven, more reagent consumption, and poor results.

Steam Boiler Gas tight Details need in the industry is a kind of oxygen trimming device for boiler for heat treatment apparatus, but the use of gas is gas steam boiler water is evaporated into steam in order to achieve the thermal processing of a workpiece, which is an apparatus commonly used in the industry we can often see the shadow of this device. However, in peacetime, when there are a lot of use of safety regulations should be noted that only pay attention to these in order to effectively ensure a good working smoothly. so what needs to pay attention to it, today gave you tell us, first of all is to remember do not open the lid of the boiler in the processing time, so as not to spill the steam burns themselves, we all know that steam is liquefied bring us a lot of damage, so in use the time to pay attention. Second, in peacetime, gas steam boiler production time is pay attention to good equipment working environment, and only use to ensure safe production in a safe environment, cantilever crane manufacturers said that we are operating when we must pay attention.

Why Oxygen Trim Should Be Part of Your Boiler Room

Sep 05, 2019 · Oxygen trim (O2 Trim) is a system that constantly monitors your boilers combustion. Unlike your car, your boiler has the ability to run properly without it, so what are the upsides to it? This system can adjust your air fuel ratio based on what its supposed to be and triggers alarms or lockouts should the combustion deviate from proper levels.

Technical advice on boiler combustion control

The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result, the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra oxygen reached this temperature by receiving fuel energy in other words, fuel was purchased to heat the extra oxygen.

Improving Boiler System Efficiency: O2 Trim

O2 Trim senses these changes by measuring the oxygen in the exhaust of the boiler and sending a message back to the servo control system, which will then correct for the changes. These precise adjustments significantly reduce the amount of fuel needed to fire the boiler over time, resulting in energy savings as well as increased operating efficiency.
