How to prevent gas hot water boiler water heating boiler for colombia explosion gas hot water boiler belongs to the category of special equipment, thermal equipment and is a frequently in high pressure high temperature state, it is inevitable some small problems that may occur during operation, this is normal; but if not in place or because of negligence, they are likely to make the boiler exploded. So, for safety equipment and personal safety, we have to understand some common sense prevention hot water boiler explosion. 1, hot water boiler furnace explosion prevention occurs first on the boiler design, should be strictly thermodynamic calculation and strength calculation in accordance with the requirements of GB50041-1992 "boiler room design specifications", the structural arrangement should be reasonable, material quality should meet the requirements. Boiler manufacturing, construction plans should ensure compliance with national quality boiler scale delineation. Boiler safety accessories should be complete, agile and reliable, and maintenance schedule, often check on the failure of the attachment timely replacement. Schedule for maintenance of the boiler, the outer part of the boiler maintenance, subject to the existence of timely repairs and reconstruction to ensure test quality standards. 2, prevention of fuel, gas hot water boiler furnace explosion at the point of blast furnace to double-check each gas line, oil line is tight (leak), pressure is normal, Installation and reconstruction of new oil and gas pipelines necessary to purge and clean. Check the ignition lead before the drum whether the fan has to take the air 5 ~ 10min, after ignition failure to analyze the reasons, and then restart the ignition process to take the air ignition. Boiler use permit and inspection certificate did not apply for the boiler, furnace stokers right to refuse point. Enterprises should choose a fireman permit manipulation of experienced fireman point-furnace work, fireman staff should strengthen the inspection tour, identify problems in time to prevent the flame; flame once found, should immediately cut off fuel. Boiler installation should be controlled protection device, comprising an automatic ignition, flame protection, automatic adjustment of combustion and the necessary alarm chain protection.
2018ISH heating HVAC industry event, fast Boiler "Thalia T7" was set aside to hold the event May 23, ISHChina & CIHE China (Beijing) International heating ventilation air conditioning, heat pumps fresh air and home comfort systems and technology exhibition in Beijing International Exhibition hot center opening.
Gas-fired steam boiler water heating boiler for colombias and coal-fired steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas and coal-fired steam boiler steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answers to the same model or coal-fired steam boiler energy saving compared to steam boilers, we can roughly be calculated next-ton per hour boiler work at full capacity to 150-160Kg according to the market value of coal fuel, and gas to around 80m3 of gas. A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.
Tail secondary combustion flue how to deal with the phenomenon of a sharp increase in rear of the boiler water heating boiler for colombia flue secondary combustion flue temperature location and later. 2, the furnace, the flue abrupt change in negative pressure, flue gas is not tight at the smoke, the Mars. 3, air preheater large current swing bearing housing temperature, severe Jam occurs. 4, air preheater fire alarm issue. 5, steam temperature, economizer outlet water temperature, the air temperature rises abnormally. 6, induced draft fan vanes automatically open a large, Fan current rise. 7, as the combustion side, both sides of the smoke temperature difference increases. Reason 1, through the coarse fine grinding coal, coal poor uniformity, improper adjustment of combustion, combustion of fuel is insufficient, serious mechanical incomplete combustion, and high levels of combustible ash accumulated in the back pass. 2, an oil burner or an oil poor atomization, so that unburned droplets deposited in the flue. 3, prolonged low load operation of boiler, the furnace temperature is too low or too small amount of excess air resulting in incomplete combustion of coal or oil accumulated in the tail. 4, after the shutdown of the fuel leakage into the furnace and accumulates or after shutdown and to insufficient MFT furnace purge unburnt coal or oil accumulation at the end of the tail. 5, soot blower failure, long-term put into operation is not normal. 1 process, when a slight secondary combustion, exhaust gas temperature does not rise within 20 ℃ normal smoking temperature should be checked immediately paragraphs, the combustion site and judge whether the secondary steam soot blowing. (When the exhaust gas temperature rises to 250 ℃) 2, the operation of the back pass and then generating boiler combustion boiler operation should be stopped immediately, immediately stop sending, ID fan and turn off all the smoke and steam soot blowing air damper fire. 3, if the economizer afterburning, until the storage tank level control valve blocking off without pressure, flow rate of feed pump motor start 150t / h Sheung be cooled. 4, air preheater heating surface of the secondary combustion air preheater normal operation, normal operation of the air pre-heater holder; air preheater Jam occurs, the main drive motor and the auxiliary drive motor trip, contact maintenance manual plate moving continuous air preheater rotor. Soot blowing steam into air preheater for extinguishing, into the air preheater for fire extinguishing can not be extinguished. 5, the economizer outlet water temperature close to the inlet temperature (at the economizer secondary combustion), the air preheater inlet gas temperature, exhaust gas temperature, the hot air temperature is lowered to less 80 ℃, each one hole, and the hole is no longer Mars smoke and soot blowing steam stops coming out after water or fire. Open hole inspection manhole and inspection to confirm the secondary combustion goes out, after the flue vent door open to drain water inside the smoke flue opening for ventilation air damper. 6, to be re-combustion is resolved, the flue temperature does not rise and fall when stabilized, before slow regulation of the air, smoke baffle, the necessary air cooling and purging.

A condensing boiler makes the most sense with radiant heat, though baseboard and conventional radiators work well also. Steam radiators do not AFAIK offer themselves to be heated via condensing boilers. Note, there is a strong preference away from condensing oil boilers due to the corrosive nature of US fuel oil (condensing gas boilers are OK).Learn More

Your boiler is a block of iron that wants to remain warmer than the spent flue gasses (140F for gas, maybe 130F for oil). Let's call it 140 to be safe. If you set your boiler operating temperature below that for extended periods the flue gasses will condense, form acidic deposits and eat the boiler.Learn More
