Problematic fired boiler (1) Henan small boiler gas boiler should be noted, by the Henan coal into gas boiler, i.e. the original becomes a negative pressure is now slightly positive pressure combustion burner, the furnace must be noted that the structure and the sealing wall problem; (2) prevent explosion of the furnace, a gas fired boiler furnace to Henan, when defective or incomplete combustion of fuel atomization gas in the furnace or heating surface of the end aggregate, fire or explosion occurs, and therefore, in appropriate sites shall boiler explosion vent means, while the control program should be added to the ignition and flame protection device of automatic control, to ensure safe operation of the boiler; (3) the selection and arrangement of the burner close to the furnace in the form of, should the flame in the furnace better fullness without forming dead air; adjacent flame of the burner to avoid mutual interference; low load flame holding in the furnace central position, offset from the center of the furnace to avoid the flame center of symmetry; unburned gas-air mixture is not in contact with the heated surface , to avoid the formation of incomplete combustion gases; hot flame to avoid high-speed heating surface erosion, in order to avoid excessive heating surface so that the wall strength of overheating. Burner arrangement also consider the gas pipe and duct arrangement, easy to operate, inspection and maintenance; (4) Mechanized layered coal-fired boiler, gas boiler to change Henan, first removing its longitudinal arch, taking into account the increase in the bottom heating surface to replace the grate, grate to prevent overheating burn; (5) gas velocity Henan convection heating surface is not limited by the gas boiler ash abrasion conditions, gas velocity can be increased properly, so the convection heat transfer heating surface coefficient increases, without increasing the heating surface of the boiler, can increase the pressure of the boiler, steam-water separation capability should be noted that at this time means the pot to ensure the quality of steam, hot air for the boiler had particularly important.

After installation and commissioning fast Boiler professional and technical personnel, two hot water boilers to provide our bodies quickly into the orbit of the normal operation. Meanwhile, the design of energy-saving equipment also effectively improve the thermal efficiency of the boiler, saved us a huge amount of fuel costs. --customer feedback

Mature technology in biomass boiler, our SZL series chain grate boiler widely available renewable energy technology that generate steam from 6 to 40 ton to any industry factories, facilities, plants, etc. What’s more, our ZG Boiler can can supply larger capacity and high pressure circulating fluided bed, power plant boiler, biomass boiler, produce steam for electricity or other requirements. A fully automated operation system, similar to those used for conveying feed and grain on farms, delivers biomass pellets from an outdoor silo to the boiler’s hopper. At a rate predetermined by user-controlled settings, a fuel-feed system then delivers the pellets to a combustion chamber. Pellets are burned using staged combustion air injection (a process that reduces NOx ). A cyclone separator knocks out particulate matter that is then removed by an on-line, automated mechanical cleaning and ashremoval system. Usually, biomass fired cfb boiler has higher thermal transferring efficiency than chain grate boiler. And both of them can burn mixed fuels like wood pellet and coal; bagasses and coal; palm shell and coal etc.

Horizontal hot water boiler a few precautions, overpressure accident 1 boiler, coal steam boiler manufacturers sialkot overpressure phenomenon of (1) a sharp rise in steam pressure, the pressure exceeds the allowable working pressure gauge pointer over the "red line" is still working pressure safety valve l high. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified. Second, an accident boiler water, boiler water shortage (1) below the minimum safe water level line, or can not see the water level, the water level gauge glass (plate) as a white. (2) as a full-color water level gauge vapor instruction color. Low water level alarm signal (3) water level alarm occurs. (4) low water interlocking means, the water level should be below a prescribed value blower, Fan, grate reduction motor stops running. (5) a sharp rise in the superheater steam temperature, higher than the outlet steam temperature. (6) boiler exhaust gas temperature rises. (7) the water flow is less than the steam flow, causing Should the water tube due to tube cracking or economizer, an opposite phenomenon occurs. (8) When a serious water shortage, can smell the burnt smell. (9) When a serious shortage, the door can be seen from the red-hot waterwall tubes. (10) a serious water shortage, the furnace tube may rupture, then can hear the explosions, smoke and steam from the door, watching spray the fire door. 2, boiler water treatment (1) through the "waters", sentenced to severe water shortages, emergency shutdown must be prohibited blind to the boiler feed water. (2) through the "waters" sentenced to a slight lack of water, it should reduce fuel blast, the wind, and slowly feed water. Third, full water boiler 1 accident phenomenon (1) above the maximum allowable water level line, or can not see the water level, the water level gauge glass (plate) dark color boiler filled with 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, steam 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.
