hot water boiler heating

Sewage and sewage boiler shutdown 1 "diligence row, row of small, uniform discharge" principle, each class at least once sewage. 2, the sewage should be conducted under low load, high water level, or shutdown, in which case a slow flow of boiler water, slag tends to accumulate dirt, good discharge effect. 3, intermittent discharge operation should be short, every time the sewage water level drop in the furnace preferably 20 ~ 40mm. Each group has a series outfall way valve, a drain valve. The drain valve is fully opened when the first operation, and then the gate valve slightly open, sewage is completed, the gate valve to close slowly, and then close the drain valve, blowdown if there is an impact sound will immediately shut valve small, impact sound disappear until the sewage pipes, to open big. Sewage should not be too long, so as not to affect the water cycle. (G) 1 shutdown, shutdown temporary failure: after shutdown, to conduct inspection in ensuring the safety of the situation. 2, temporarily shutdown: the case of a planned shutdown in case of holidays and so on, should pay attention to the maintenance of the boiler. 3, complete shutdown: There is a plan for a regular inspection and maintenance of the boiler shutdown. 4, emergency shutdown: 1) boiler water level below the minimum level table visible edges. 2) increasing water supply and other measures, but the water level continues to drop. 3) boiler water level exceeds the highest visible level (full of water), turn on the water can not be seen by the water level. 4) to pump water system failure or malfunction, not water to the boiler. 5) water gauge or safety valve all the failures. 6) Set all the failures in gauge steam space. 7) boiler component damage and endangering the safety of operating personnel. 8) combustion equipment damage, he or furnace wall to be red-hot boiler structure such as a serious threat to the safe operation of the boiler. 9) other unusual circumstances endanger the safe operation of the boiler. When the boiler pressure parts found leaks, furnace coke heavy, metal-temperature heating surface and can not return to normal as well as other major issues, should stop boiler operation.

Fast boiler strong technical team and perfect after-sales service to our left a deep impression, the successful completion of the boiler installation and commissioning work at a predetermined period. The company offered me two Taipower heating steam boilers, combined with the actual situation of our company, as we save a lot of fuel costs, thanks to fast boiler provides us with such high-quality products and peace of mind. --customer feedback

Waste heat recovery boiler applications:

Traditionally, waste heat of low temperature range (0-120 °C, or typically under 100 °C) has not been used for electricity generation despite efforts, mainly because the waste heat boiler efficiency is rather low (max. 18% for 90 °C heating and 20 °C cooling, minus losses, typically ending up with 5-7% net electricity). In general, waste heat below 100 °C could be used for the production of bio-fuel by growing of algae farms or could be used in greenhouses or even used in Eco-industrial parks.Waste Heat of medium (120-650 °C) and high (>650 °C) temperature could be used for the generation of electricity or mechanical work via different capturing processes.

Food processing plants most use coal-fired boilers to provide steam needed for production. For a long time, coal-fired boiler boiler industry occupies 90% utilization, the coal price is not high, suitable for economic development is relatively backward areas, and less demanding on the coal boiler, use low heat, low-quality large ash coal, by the boiler industry favorite. But with coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boilers faces comprehensive reform issue or banned.

Troubleshooting a Gas-Fired Hot Water Boiler

Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").
