lng low pressure steam generator

Environmental characteristics and working principle of the boiler burner in recent years, with the emergence of environmental progress boiler burner and integrated development of the regenerator, as well as fast-acting valves and electronic control system of the program longer life a significant savings the new regenerative energy and environmental protection boiler combustion engine has been started in some foreign high-temperature industrial kiln. First, the features of the new green regenerative burner boiler 1, 90% of the heat recovered from the flue gas can be reused, thus saving 50 to 60% of the fuel. 2, thermal properties quite stable. Not affected by the quality of the furnace flue. 3, may use natural gas or some other fuel gas, light oil or heavy oil combustion. 4, compact structure, easy installation, a short payback period. 5, to improve the working conditions of the furnace, greatly reducing the maintenance of the furnace. 6, can be formed in the furnace - a good temperature distribution, thereby improving product quality and production capacity of the furnace. In the United States, Britain, France, Japan, West Germany and other industrialized countries, at least 500 such devices have been used on industrial furnaces. Second, the composition and working principle of environmental protection regenerative burner of this new heat recovery boiler burner principles of environmental protection boiler flue gas heat recovery is achieved by a small regenerator with the self. 2 is equipped with a set of gas burners in a heating furnace, each burner in the lower portion, a small accumulator is mounted a ball filled with AL2O3, an air inlet connected to the upper space of the regenerator and burner , in addition to the bottom of the heat accumulator is connected via a combustion air pipe and an outer valve, the valve is further connected via another exhaust pipe. In operation, assume that the furnace temperature reached 900 ℃, air enters the front of the burner used (valve opening) from the bottom of the regenerator, increases to a burner fed by 8O0 ℃ filler layer inside the regenerator temperature, gas the fuel discharged from the high-speed burner rear axially into the furnace with the combustion air is mixed with the high temperature, environmental protection boiler burners installed to the furnace wall at an angle, so that a high speed gas can be injected into the combustion furnace flue gas and forming vigorous stirring to achieve uniform temperature in the furnace. Since the combustion process of the furnace is in the form of a closed state, the fuel gas into the combustion furnace exhaust gas should be balanced, the flue gas discharge outlet from another burner reverse flow from the air inlet through the regenerator packing layers of It flows from top to bottom, AL2O3, and the ball is in direct contact with high temperature and flue gas heat exchanger, and a temperature gradient in the order of packing layers. Reaches the lower flue gas is cooled by heat exchange, and then (valve opening) from the exhaust port through the exhaust pipe discharge (when the air inlet valve at the bottom of the regenerator is in the closed state). In this way a few minutes until the continuous operation, the temperature rises AL2O3 balls, reaches the outlet exhaust gas temperature (e.g. 150 ~ C). In contrast, since the front of the regenerator into the combustion air is cooled to remove heat, the temperature of hot air sent to the burner is gradually lowered (e.g., to about 700 ℃). Time to dig through a temperature program control system, two burners arranged together exchange valves 6, can be formed so that a work order: starting with the lower portion of combustion air into the regenerator, after the heating temperature reaches the burner, while discharging fuel gas, mixed with air into the furnace combustion temperature, part of this time a flow of combustion gas is inversely behind by the burner, while the internal accumulator fill ball cooled heat while discharging. Since this switching operation is automated, and thus the whole combustion process is carried out continuously. With this new environmental Burner preheating temperature of the air just below the gas temperature 100 ~ 200 ℃, the flame temperature is generally higher than 2200 deg.] C, the flame temperature results in cleavage of the fuel molecules (polymerization) of action, resulting in brighter flame more conducive to heat the furnace.

The steam generating boiler has to produce steam at the high purity, pressure and temperature required for the steam turbine that drives the electrical generator. Each thermal power plant need lng low pressure steam generator, 35 ton corner tube coal fired steam boiler in ZG Brand is a good choice.

This time, the party quickly staff also two school children brought nearly this reading materials, together with the 2017 contributions, a total of two school books donated more than 3000, to add more color to the world of children. Fang fast philosophy tells us that the work should be "fine industry", Jingye is to "+ dedicated professional", it requires us to "long-term focus and become an expert." Shu ten years, a hundred years trees, love must not be "superficial", and to focus on "little", and stick to it. This down a few years later, bit by bit we will help to gradually bear fruit, harvest fruit.

Electric heating steam boiler water level gauge how to deal with each calibration level indicated correctly judge whether the lng low pressure steam generator dry biomass. Biomass can not be determined in a steam generator or water when filled with water, turn on the water faucet water level gauge can be opened, if not pan out the water, indicating water shortage accident, otherwise it is full of water accidents. For the embodiment allows a small biomass called water steam generator operation, water may be first called, the steam generator is determined biomass mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and larger circles fire biomass steam generator. Otherwise it can not be called biomass steam generator water, because it will delay the time of the accident biomass steam generator water treatment, the worsening of the situation. When the steam generator slight dry biomass, should reduce the fuel and air, reduced combustion, biomass steam generator and the water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then examine biomass steam generator there is no abnormality, the following confirmation before they can resume normal biomass steam generator operation. When biomass steam generator severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of the steam generator water shortage in raw materials, the use of intermittent water several times, each time a small amount of water replenishment way to cover up the accident biomass steam generator. This practice is very dangerous. If biomass steam generator water not too serious cause biomass boiler leaks. If biomass steam generator can cause serious water shortage biomass steam generator explosion. Only the steam generator biomass and natural draft cooling pot temperature dropped to below 70 ℃, water only slowly.
