Chain grate hot water boiler is an industrial or utility boiler that generates thermal energy by burning coal that is put into the firebox. Bituminous , anthracite, lignite, lean coal, coke,cotton stalk,groundunt shell,palm fiber, saw dust, bagasse, rick husk are available for chain grate hot water boiler. Chain grate hot water boiler for sale is still very necessary and popular in areas where the oil and gas are beyond.It plays a significant role in fuel costs savings.

How to make the current higher operating efficiency gas boiler, small coal-fired boiler gas boiler gradually, alternative clean energy biomass briquette boilers and other boilers, and of which the operating efficiency of a higher gas boiler, because gas-fired boiler fuel combustion rapidly generate of power, compared with coal-fired boiler efficiency to be higher than 20% and less pollutant emissions, for maintaining more favorable environment. Improve the thermal efficiency of gas boilers, gas-fired boiler allow more economical operation of the boiler industry is the goal. The following are several ways to improve the thermal efficiency gas boiler: 1, the design of the boiler must be reasonable and unreasonable boiler structure, will result in waste heat, or the heat consumed in the loop on the way in. 2, around the pipe connecting the boiler should always check if there is a leak place, immediately carry out maintenance shutdown to prevent leakage phenomenon. 3, gas boiler can also play a role in the heat recovery, the circulating water collected back for re-use, this is the method of improving the combustion efficiency of the boiler.

The steam boiler can be divided into three kinds according to the fuel (electricity, oil, gas), such as electric steam boiler, oil steam boiler, gas steam boiler, etc. According to the structure can be divided into vertical steam boilers, horizontal steam boilers, small steam boilers are single, double-return vertical structure, large-scale steam boilers are mostly three-way horizontal structure. If according to the classification criteria above, there are a lot of steam boilers, take an ordinary fast-packed 4-ton steam boiler. Water is heated into steam in the drum and heat is emitted by fire in the furnace, which is the principle of the steam boiler. Steam The combustion part of a steam boiler consists of a chain grate and a drive device, together with a combustion chamber composed of a boiler rack on the grate frame. Surrounded by refractories. Coal from coal hopper, there are coal gate to control the thickness of coal seam while sealing the front of the air. The lower part of the combustion chamber is the place where the blast enters. This steam boiler has great resistance and needs forced blast. The cinder of a steam boiler, discharged from the back of the grate through Eagle's mouth iron and sent out of the furnace by a slag extractor. Steam boiler flue gas from the back of the boiler, by the steam boiler drum one-way smoke pipe forward, from the two-way smoke pipe back to the rear, then into the dust collector to separate ash, and then through the induced fan from the chimney exhaust Out. The above is the working principle of steam boiler, of course, the operation of steam boiler without other equipment, such as the induced fan not only undertake the task of exhaust flue gas, but also the steam boiler negative pressure operation necessary. There are also pressure vessels, thermometers, safety valves, pressure gauges, pumps, steam pumps, etc. All are essential for steam boiler work. Pump leak problem. The actual output flow rate of gear pump is smaller than that of theoretical flow due to the leakage of gear pump in the process of operation. The main leakage channel of gear pump is through the gap between the two sides of gear and the cover plate on both sides of the gear, which is 75% / 85% of the total leakage of the pump. Radial clearance leakage between gear top circle and inner hole of pump; clearance leakage through gear meshing. Because of the leakage of gear pump, the output pressure does not go, which affects the range of use of gear pump. In order to solve the problem of low output pressure of gear pump, the way of adding floating sleeve or elastic baffle on both sides of gear pump is adopted to reduce the leakage of gear pump and improve the output pressure of gear pump. Radial force imbalance problem. In the working process of the gear pump, the pressure on the outer circle of the gear is not equal, which results in the radial unbalance force at the shaft and bearing of the gear. This radial imbalance will accelerate the wear and tear of the bearing, reducing the bearing The service life also may cause the gear shaft to deform, causes the tooth top and the pump body inner hole friction, damages the pump body, causes the pump not to work normally. The common solution is as follows: (4) opening pressure balance slot on pump, leading high pressure oil to low pressure area, but it will increase pump leakage and affect pump volume efficiency; (2) reducing the size of the pressure chamber, reducing the pressure area acting on the gear teeth, and thus reducing the radial unbalanced force.

Hot water boiler heating industry is our essential equipment, gas fired hot water boiler manufacturers industrial brunei water provided by the party fast flotilla, high thermal efficiency direct savings on fuel costs of inputs for our company, the intelligence facilities let the boiler run more convenient and effective to reduce the labor intensity of fireman people. --customer feedback
