After the Horizontal Boiler flame-out and shut-down,we should pay special attention to prevent the furnace explosion.Furnace fuel supply must be cut off immediately,and check the gas supply (supply and return oil) solenoid valve to ensure that it is in the
closed state,and then manually shut down all running burner fuel supply valve.Operation action should be fast to avoid furnace explosion caused by that fuel continues or resumes to supply.And identify furnace flame-out reason at the same time and exclude faults found,and then start to do the preparatory work.Before starting,we should strengthen the Horizontal Steam Boiler ventilation, start to purge,purge time is more than 5min,then ignite according to the operating rules.
If the flame-out is caused by fan failure,should quickly close the fuel supply line valves doors,paying particular attention to fuel leakage caused by that the valve is not closed tightly. At the same time,start the ventilation and purging of furnace and gas duct in accordance with the emergency shutdown treatment.After the fan resumes the operation,then begins to ignite according to steps.

what affects water tube biomass boiler heat efficiency
Biomass water tube boiler for sale is the widely used boiler style in recent years. This boiler burns biomass pellet, clean & low emission, high heat efficiency. While some heat losses will produce that affects boiler heat efficiency.
1. Heat loss due to incomplete combustion of solids: mainly because in the combustion of solid fuels biomass boilers from the grate without burning an exothermic and fuel leak fuel contained in ash after combustion of combustible substances could not be released in full the losses caused by the heat.
2. Heat loss: biomass chain grate boiler furnace wall surfaces, heating surface, drum sets, boxes and other apparent loss in case of air cooling oriented.
3. Exhaust gas heat loss, heat contained in a row of birth biomass boiler flue gas not consumed by boilers converted to losses caused by the steam or hot water.
ZG manufacturer of biomass boiler supplies boiler with double transverse barrel structure, completely overcome the boiler barrel bulge phenomenon of overheating caused by exposed directly to the furnace, heating surface layout more rational. Furnace on both sides of a membrane water wall structure, which ensures the sealing of furnace and improving the thermal efficiency of the boiler.

Two Reasons Why Biomass Fired Boiler Leakage
As energy price is increasing and pollution is more and more serious, more enterprises seek green and environmental protection fuel, biomass as the ideal energy is to replace some fossil fuels to be used in industrial boilers.
A green biomass fired boiler is a high efficient and environment-friendly product that can easily burn shaped biomass fuel or both pure and mixed coal with its economizer in the rear. Fuel: Biomass fuel forming; rice husk, bagasse, coconut shell, straw, coal and biomass blends
Biomass fired boiler might occur leakage that affect its efficiency. Here are the Two Reasons Why Biomass Fired Boiler Leakage.
Oxygen corrosion
For the water tube biomass fired boiler pressure parts,the water side is mainly electrochemical corrosion,the fire side (or flue gas side) is mainly chemical corrosion.The oxygen corrosion belongs to electrochemical corrosion, it is mainly caused by the dissolved oxygen in water.At room temperature,the dissolved oxygen concentration is about 9.1mg / L,according to the GB1576-2001 "industrial boiler water quality" requirement ,the rated steam pressure should not be more than 1.0MPa,the dissolved oxygen concentration should not be more than 0.1mg / L,otherwise,it is likely to lead to metal corrosion.
Chlorine Corrosion
The chlorine ion exchange will cause high rate of metal corrosion,which is due to that the chloride ion radius is small,and it is typically activated anion,it is more active when the oxygen exists.With the operation of the boiler,if the boiler water salinity increases,the concentration of chloride ions rise constantly,there will be more deposits at the bottom of the boiler,in smoke pipe and the water cycle weak areas.
