delicate processing natural gas hot water boiler manufacturers

Beiqi Panther car 6 tons of steam condensing one fuel gas steam boiler project has been successfully completed. This series boiler adopt advanced design concepts, using the waste heat of flue gas cascade, with the use of the condenser and the economizer fully absorb the waste heat in the flue gas, the boiler efficiency has been greatly improved.

How to make boilers more energy-efficient? (Common measures) 1. boiler design of energy-saving measures (1) boiler design, first of all should be a reasonable selection of equipment. In order to ensure safety and energy conservation in the industrial boilers meet user requirements, should be due to self-select the appropriate boiler design boiler type in accordance with scientific and rational selection principles. (2) when the boiler selection, but also the right choice should be based on the type of boiler fuel boiler, industry, geographical install a reasonable choice of fuel type. Reasonable blending the coal moisture, ash, volatile matter, particle size and other combustion equipment meet the requirements of the importing boiler. At the same time, we encourage the use of new energy sources such as straw briquettes as an alternative fuel or blended fuels. (3) In selecting fans and pumps, to select a new type of energy-efficient products, can not choose backward out of the product; boiler operating conditions by matching pumps, fans and motors, to avoid the phenomenon of the "big horse car", the current inefficient use, a large auxiliary energy consumption, should be modified or replaced with energy-efficient products. (4) a reasonable choice of parameters boilers generally at efficiency of 80% to 90% of the maximum rated load, as the load decreased, the efficiency also decreased. Capacity boilers generally used with greater than 10% of the actual vapor on the line, such as when the selected parameters are not exactly according to the standard series, the boiler can choose a higher gear parameters. Auxiliary boiler selection also refer to the above principles, to avoid the "big horse cart." (5) reasonably determine the number of boiler principle is to be considered normal boiler maintenance shutdown, and pay attention to the number of boiler boiler room, no more than 3 to 4 units. (6) a boiler economizer SCIENCES designed to reduce heat losses and improve the thermal efficiency of the boiler, economizer heating surface disposed in the boiler backpass, boiler feed water is heated by heat of the flue gas, to save energy, the installation Xingmei after, a feedwater temperature increase the temperature difference between the boiler water and feed water is reduced, reducing the thermal efficiency of the boiler feed water is generated. Countries: where <4 t / boiler flue gas temperature is not greater than 250 ℃; ≥4 tons / boiler flue gas temperature is not greater than 200 ℃; ≥10 tons / boiler exhaust gas temperature is not greater than 160 ℃, province or should be installed coal is.

Steam boiler is too many forms, 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. Say the boiler first the pot. The boiler is a drum boiler with water cooling. Two return pyrotechnic tubes are arranged in the left and right parts of the drum, and the front cigarette box in the front part of the drum is turned back. Between the drum and the bottom box, there is a drop tube and a water-cooled tube, forming the frame of the combustion chamber. There is a steam separator on the top of the drum to reduce the water produced by steam. The heating surface of the boiler is the lower part of the drum, water-cooled pipe and pyrotechnic pipe. The combustion part consists of a chain grate and a drive device, Add the boiler frame on the grate of the composition of the combustion chamber composition. 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, and this kind of boiler has great resistance and needs forced blast. Cinder, discharged from the back of the grate through hawk iron and sent out of the furnace by the slag extractor. From the back of the boiler, the flue gas goes forward from the first return pipe of the boiler, the second return pipe returns to the rear part of the boiler, and then goes into the dust collector to separate the ash, and then through the draught fan, it is discharged from the chimney. The induced draft fan is not only the exhaust gas, but also necessary for the negative pressure operation of the boiler. Steam boiler is pressure capacity Device, safety device is necessary. Essential water level gauges, pressure gauges, safety valves, thermometers, electric pumps that can replenish water under pressure, and steam pumps that can also be used in the event of power outages. Boiler water must be softened and water treatment equipment.

Performance horizontal oil-fired boiler is now full of water and the handling of horizontal steam boiler steam boiler accident refers to a horizontal design, in accordance with the fuel divided into horizontal electric steam boilers, horizontal steam boiler fuel, gas steam boiler and lying horizontal coal-fired steam boilers. Horizontal steam boiler flue gas flow due to the long, slow smoke, high thermal efficiency, it is very energy efficient. Horizontal steam boiler filled with water treatment and now the performance of an accident, the phenomenon of (1) the water level is higher than the maximum permitted cable, or can not see the water level, water table within a glass tube (board) Color dark boiler full of water. (2) all of the water phase as a color level gauge indication color. High-water alarm signal (3) water level alarm occurs. (4) decreased superheated steam temperature. (5) water flow is not normally greater than the steam flow. (6) water in a large number of sub-cylinder, severe trap operation. (7) with a large amount of water steam severe, increased salinity, water hammer occurs in the sound of the steam pipe, the steam connection flange outwardly dripping take place. 2, boiler full of water treatment rinse water table, determined to be minor or serious full of water full of water. Method: Close water table, the water pipe connected cock, then open drain cocks As can be seen from the decreased water level, indicating a slight full of water, the water supply is stopped, the drain valve open, put to the normal water level. Such as severe filled with water due to take emergency shutdown measures.
