Improve the life of the cfb ash utilization boiler surfur four tips boiler because of the small size it is often buy a home when heating equipment users, but any device has its own life, in order to extend its life, we can use the following tips for: 1, control the boiler heating rate to avoid excessive thermal stress, metal fatigue. 2, when the water supply oxygen to the apparatus to prevent oxygen corrosion, deterioration of water quality if the furnace, a portion of the boiler water may be drained. 3, water quality control, to prevent serious internal boiler fouling, avoid uneven heating problem. 4, the control iron, heating boiler control, the boosting speed, to prevent the boiler burst. These four tips will help improve the life of the boiler, in addition we also need it to do maintenance and repair work in their daily lives, if used improperly or improper operation, or will bring a lot of problems.
In order to implement the CPC Central Committee stressed that the spirit of environmental protection, and improve ambient air quality, Zigong City, Sichuan Province, along the beach area Market Supervisory Authority vigorously upgrading coal-fired cfb ash utilization boiler surfurs, coal-fired and successfully completed in 2018 within the jurisdiction of the county built-up area boiler out of the task.
It is reported that, along the beach area at the beginning of market Administration issued the "Notice on coal-fired boilers to establish long-term mechanism of control", strictly review the coal-fired boilers within the jurisdiction registered good customs, the illegal construction of coal-fired boilers firmly prohibit the registration, not be released "using the registration certificate." According to statistics, in 2018 a total cancellation of 38 coal-fired boiler units, which use the unit actively kills six, lost to corporate announcements of cancellation 32; guide the completion of the upgrading of clean energy companies working two boilers. Coal-fired boiler built in the region's county area have been "cleared."
This year, the beach area along Market Authority will also continue to promote the long-term control mechanisms coal-fired boilers, the "look back" checks that have been written off non-removal of equipment companies to speed up the removal of facilities and equipment, have been banned to prevent the resurgence of coal-fired boilers; non coal-fired boiler built in the county area, program of work, to prevent companies using untested boiler, timely elimination of scrap cancellation of registration.
Determination of Gas cfb ash utilization boiler surfur water on a gas introduced through a gas boiler incineration operations: incineration of carbon-based fuels thereof containing oxygen, carbon dioxide and steam occurs, escape from the top or the side of the stack, it referred to as a flue. Such planning trouble is that a lot of heat can escape from the exhaust gas. Escape the heat means wasting energy, it will cost you money. Another system is known as the condensing gas boiler, the flue gas passing through a heat exchanger, which heats cold water from the heat sink back, the exhaust gas temperature after the recovery of only about 60 ℃, so heat power probably increased by about 10%, savings of natural gas by about 10%, while the energy recovery process, you can also reduce harmful gas emissions, reduce environmental pollution. Condensing gas boilers like this can reach more than 90% power (more than 90% of the original energy into energy to heat your room or hot water). How to compare the traditional and the modern, non-condensing gas boiler condensing gas boiler 1, different incineration technology. Condensing boiler operation under normal operating conditions, gas and fresh air was mixed burning, burning completely high power, low emission targets. However, the practice is not possible to reach the gas-fired boiler burning thorough mixing ratio, a large heat loss, but condensing boiler does not present this problem. Condensing boiler with a new technology, high cost, so its price will be higher than the average boiler. 2, the use of different age. Since the conventional gas boiler incinerator, burning chamber and other key components, plus water quality and other issues, will make use of the product life decline. With inlet incinerator normally condensing boiler service life due to its advanced technology, the use life is generally greater than a conventional gas boiler. 3, different energy saving. Usually conventional gas boiler heating power can reach only 92%, because the conventional high-temperature exhaust gas boiler, the fuel burned in the water occurs when superheated steam conditions in the flue gas, is lost with the flue gas from the stack, reducing thermal power. Condensation boiler thermal power is greater than 95%. During incineration may be the exhaust gas temperature is reduced to 50 ~ 70 ℃, it is very energy efficient. Water quality measurement process and the measurement gas boiler 1 chloride specification taken in boiler water 100ML measuring cylinder 250ml conical flask, to participate in 2-3 drops of phenolphthalein indicator, was pink, then titrated with sulfuric acid to colorless, participate 2-3 dropwise potassium network indicator, standardized silver nitrate solution was titrated to red jujube, the volume number of the silver nitrate consumed record, namely 35.5 multiplied chloride specification: 4002 Determination of chloride less alkalinity boiler water take measuring cylinder 100ml to 250ml conical flask, to participate in 2-3 drops of phenolphthalein indicator, the solution was pink, was titrated with sulfuric acid to regulate just colorless, then add 2-3 titration methyl orange indicator, titrated with sulfuric acid continued to orange red stopped, the volume of sulfuric acid consumed number record, the size of this measured value is equal to 3 hardness alkalinity boiler water 100ml measuring cylinder taken to a 250ml Erlenmeyer flask, to participate in a few grains Los black T indicator, then add 2 -3 dropwise ammonia - ammonium chloride buffer solution with standardized EDTA solution was titrated to a wine red solution turns blue end record number EDTA solution volume consumed, this value is equivalent to the size of the boiler water hardness. Specification: Hardness: Determination steam oven 0.6mmol per liter or less per liter of the water heater 4 pH measured 0.03mmol Specification PH test paper: PH value: 10-12
Both of them work with a high efficiency. Compact structure and easy installation ensure efficient, clean, economic, safe and stable cfb ash utilization boiler surfur operation, therefore, it is widely used as an energy-saving and environment-friendly equipment in industry.
The residue collected from the boiler is called CFB ash. CFB boilers in Taiwan can produce 328,000 tonnes of CFB fly ash per year. In this study, the pozzolanic characteristics of CFB fly ash were investigated by blending CFB fly ash and ordinary Portland cement (OPC).Online chat

limestone is also fed into the boiler in order to control sulfur emissions without the use of a scrubber. Due to inefficiencies in the absorption process, limestone in excess of the theoretical requirement is injected into the boiler, resulting in a highly alkaline ash.
