Determination of Gas boilers that use biomas fuel 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
The inlet speed of gas-fired hot-water boilers that use biomas fuel before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too large, the inlet velocity Fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). The diameter of the pressure pipe is too small and the length of the pipe is too long Long, will affect the dynamic transfer of pressure measurement, increase dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The flow of a pressure tap perpendicular to the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated steam boiler, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring gas pressure, the pressure splice should be removed from the upper part of the pipe to prevent dust and water droplets from entering the ignition line .Free Chat
