Henan burner safety controls in claim 1 gas boiler autoclaves jambi, gas boiler burner pre Henan Henan hair gas boiler before ignition burner, there must be a period of pre-blowing, the furnace and the flue gas blow-off I or dilution. Because the gas inevitably leave more than work within the furnace burner, if not pre-ignition and hair, there is the risk of explosion. I have to blow off a clean gas or dilution gas concentration does not ensure the explosion limits. Pre-blowing time of the furnace structure and the amount of hair is generally about 15 to 60 seconds is provided. 2, Henan gas boiler combustion engine auto-ignition combustion spark-ignition engine should be adopted, to facilitate automatic control. Available high-voltage ignition transformer arc ignition, which required energy output: voltage ≥3.5KV, current ≥15mA, the ignition time is generally: 2 to 5 seconds. 3, Henan gas boiler burner combustion state monitoring Henan gas boiler burner combustion state must be dynamic monitoring, once the flame detector flame sensed signal must be fed to the burner in a very short period of time, then the burner into the protected state , and cut off the gas supply. To the normal flame detectors sensing flame signal, neither sensitive nor slow. Because sensitive, Henan gas boiler burner combustion state if volatility prone to malfunction and slow, feedback flame signal lag is not conducive to safe operation. General requirements for the response time of a signal sent from the flame to flameout flame detector does not exceed 0.2 seconds. 4, when the gas boiler burner Henan misfiring burner ignition protection, into a gas, combustion gas ignition. Ignition operation request occurs before the gas passed into first ignition temperature field is formed, to facilitate ignition and combustion. If the misfire, flame detector can not sense the flame signal, burner protection status. Protection state from the ignition time to be appropriate, neither too short nor too long. If it is too short, a stable flame is formed too late; too long, causing a large amount of gas into the furnace when the misfire. General requirements in 2-3 seconds into a gas, flame burner flame detector signal sensed be determined, not the fire protection state, ignition combustion is maintained. 5, Henan gas boiler burner flame protection Henan gas boiler burner in the combustion process, if unexpected flameout, burner into the protected status. Since the furnace is hot, the gas enters prone to knocking, it should be a very short time into the protected state, cut off the gas supply. From the burner to the flameout into protected state, the response time of the process requires less than one second.

Determination of Gas boiler autoclaves jambi 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.
