low pressure coal fired small size boiler for fertilizer factory
Five combustion characteristics of gas combustion in The five main combustion characteristics of gas combustion of Fangkuai environmentally friendly gas-fired low pressure coal fired small size boiler for fertilizer factory in recent years, many cities frequently occur haze, which has aroused wide concern and heated discussion in the society. China is in the period of energy structure adjustment, the task is imminent, the situation is also very serious. The energy-saving and environmental protection gas-fired boiler of Fangkuai boiler is the time to show its good energy-saving effect and excellent environmental protection ability. More and more favored by enterprises. Next we analyze its advantages from the combustion characteristics of gas fuel. Gas fuel is an efficient, clean energy source, its ignition temperature is relatively low, flame can spread rapidly to each furnace. Local, rapid combustion, easy to achieve automatic gas transportation, mixing, combustion process, mainly have the following characteristics: (1) pollution is almost zero combustion characteristics, plus basically will not produce ash, The nitrogen and sulfur contents are much lower than those of coal and oil fuels, and the amount of dust contained in the flue gas produced by combustion is also very small, which is very conducive to the protection of the environment and is basically a pollution-free combustion mode. Even the areas with the strictest environmental protection requirements can be safely used, at the same time, gas fuels are piped to transport, do not produce ash, transport, storage will not occur in the process of harmful gas leakage, dust pollution and noise pollution. (2) it is convenient to adjust the combustion. The way of transportation of fuel gas is pipeline, which can adjust the gas consumption, adapt to the change of load quickly, and realize low oxygen combustion by adjusting the valve and air valve. Thus improve the thermal efficiency of the boiler. (3) good workability. Compared with oil fuel, gas fuel is piped and supplied directly, eliminating oil storage tank, daily fuel tank and other components. In particular, compared with heavy oil fuel, save heating, heat preservation and other links. Gas system is relatively simple, operation and management is relatively convenient, easy automation. (4) easy to adjust heat. Combustion liquefaction When LPG is added, adding part of the air can not only avoid part of the explosion range, but also adjust the heat generation. (5) Gas fuel also has some shortcomings, when mixed with air to a certain proportion, it will form explosive gas. And most of the components of gas fuel are asphyxiating or toxic to humans and animals, so the safety requirements are very high. The Fangkuai boiler attaches great importance to the safety of energy-saving and environmental-friendly gas-fired boilers, and strictly guards the quality level during production and commissioning. There will be no safety accident as long as there is a code of practice in the process of use. At the present stage, China is vigorously promoting the coal-to-gas project to return the people to a blue sky. . Enterprises have responded to national policies and assumed social responsibility. Warmly welcome you to our Fangkuai boiler to buy energy-saving and environmentally friendly gas-fired boiler.
The heat exchange surface of Fangkuai low pressure coal fired small size boiler for fertilizer factory is reformed reasonably: 1. The horizontal boiler is removed from the furnace arch of the original furnace, and the coal bed is covered with insulation layer and refractory brick, which is transformed into the secondary radiation surface. Vertical boilers can build radiation reactors at the bottom of the furnace and install radiation arches on the upper part of the tank. 2, control the leakage air volume of furnace and flue. It is necessary to seal the boiler's observation hole, to seal the boiler's air duct and flue, especially when the air leakage rate of brick air duct and flue is large, after changing to burning gas, it is necessary to carry on the sealing treatment, preferably to change to the metal flue. When multiple boilers share a total flue, each boiler Breakers should be installed on the flue to prevent flue gas and residual gas from the purging process from flowing into the boiler furnace that has ceased to operate. Reasonable selection of burners for Fangkuai boilers: 1. Under rated gas supply pressure, the thermal load of the burners must meet the requirements of the boilers. Combustion is complete, excess air coefficient is low, combustion temperature is high, combustion noise is small, furnace flame fullness is good, flame radiation ability is strong. 2, the load regulation ratio meets the requirements of boiler operation, and the excess air coefficient can be adjusted. 3, can realize the boiler safety technical supervision regulations issued by the Ministry of Labor automatic control project.
The first half of the low pressure coal fired small size boiler for fertilizer factory end of the oven wood oven, after completion of the coal oven according to the requirements, at this time, should increase the degree of opening of the blower, draft fan slightly open, close the door, ash door, to further improve the smoke temperature, to bake the purpose of the dry furnace wall.
The fact that we determined to achieve cooperation with the fast low pressure coal fired small size boiler for fertilizer factory is a very wise decision, after a period of time put into the boiler efficiency significantly much higher than our original boiler efficiency, significantly reduce fuel costs, the economic benefits brought by the boiler is obvious. --customer feedback
