Introduction:

The first horizontal biomass boiler in China Brand: HUAYUAN

High-end product---Longxiao series A, B, C

Technical features:

By the great effort, HUAYUAN has developed the first biomass boiler without grate. There are three kinds of hot water boilers as following:

Longxiao Series A: blue touchscreen control system, burning any biomass fuel without dark smoke.

Longxiao Series B: colorful touchscreen control system. motor frequency control system. drain the coked fuel in the combustion procession. burning all coked biomass fuel.

Longxiao Series C: large colorful touchscreen control system. intelligent control system, internet control system. drain the coked fuel in the combustion. burning all coked biomass fuel.

Characteristics:

1. Different from tradition vertical boiler, any parts of boiler could be checked and repaired. Even the fire pipes in the boiler could be replaced without boiler disassembled.

2. HUAYUAN adopts world leading patent combustion system. Boilers without grate will need no more grate transporting to solve coked fuel burning problem.

3. High temperature in the hearth could be controlled to make sure that temperature is enough high to do biomass pyrolysis gasification and complete combustion. With specially designed

airflow spraying, tar will not be attached to the hearth after longtime combustion and pipes will not be blocked by the attached tar, it will do little effect on the boiler's efficiency after long time using, this is what users will neglect. Long-time energy saving is what matters.

4. As store is directly connected to the hearth, many biomass boilers catch fire easily. Applying anti-back fire structure and back-flow prevention device, so that only biomass fuel can be put into hearth, high temperature airflow can't flow into bunker. We are equipped with safety fire protection device, even when the back-flow prevention device fails, automatic monitoring feeding system will start to force high temperature into hearth. Boiler will stop working only after cleaning all the fuels.

5. Change the traditional boiler feeding way, decrease the feeding height of bunker, increase the capacity, reduce the labor strength.

6. Traditional biomass boiler only monitor output water temperature, Longxiao series adopts touchscreen control system, clients can monitor the parameters of temperature of input water, output water, smoke, fuels in bunker, combustion in hearth etc. After the change of relevant data, it will timely remind the user of maintenance, so that to allow user to get more information about running status and energy-saving data.

7. First one to apply internet control system in biomass fuel industry, you can monitor the boiler everywhere with internet.

8. Under intelligent control, boiler will automatically operates from start-running-stop-restart. You could be an online boiler operator with high efficiency and 6 safety protection settings.

Q: Basicly, we have a boiler, thats extremly old. 24 years old. So are only source of hot water for the past 3 years was a shower. me and my mum got sick of it, and we phoned up British Gas, and they came and gave us a estimation, of ?8000. Apart from being waaaaay to expensive for us, he also told us its a Dual Pipe Boiler. We had no idea what it was, but he said that we'd have to change to a Single Pipe Boiler, and have all the floor board ripped up! Are house is a MESS, and to be honest, if its true that we'd have to have the floor boards ripped up, I'd rather move. I was wondering, is there anywhere in the UK that still sells these Dual Pipe Boiler and so that we don't have to have are floor boards ripped up.: Sounds as if someone is mixed up a little here. Boilers are basically all the same in they will run more or less whatever is attached to them. A single pipe system is probably what you have now and would most likely have been an old solid fuel system converted over to gas. You would have a single pipe running all around the house feeding all the radiators and very likely a gravity feed from the boiler to your hot water cylinder. To operate todays high efficiency boilers it requires a 2 pipe system so in effect all your radiators will be in parallel instead of series as at present.So I am sure its going to be a big job with all the boards being lifted as needed which considering the age of the existing system is probably advisable as it will probably be gunked up and will save about ?400 on having a power flush and the whole system would be new. I would suggest you ask a few local installers to quote you as ?8000 would probably do a small mansion. See if any of your friends/neighbours can recommend an installer for a start.

Q: How exactly does a fire tube boiler operate?: Fire tube boiler is one of the most basic types of boiler and the design is also very old. In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessel of the boiler. As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them. As a result steam is generated in the water and naturally comes up and is stored upon the water in the same vessel of fire tube boiler. This steam is then taken out from the steam outlet for utilizing for required purpose. The water is fed into the boiler through the feed water inlet.

Q: Well I think its a self regulated boiler? It is Worcester Bosch greenstar RI boiler, I heard it is meant to have an internal key or maybe to felxible pipes, but it doesn't??Oh and 1of the pipes coming away the main boiler has coroded if that makes a difference?Please help as it is soo cold:( :( :( :(: You must connect the boiler to a cold water line and add water to the system until it reaches the correct pressure. See pages 10 11 of this link: www.worcester-bosch .uk/cache/f... If you are unable to do this, you will have to call a boiler service company.

Q: new thermal couple...last week i had noticed the damper (automatic) was in the closed position. i nudged it a bit and it opened and the boiler fired...needed to fix a radiator pipe and shut it down...now it won't fire. mounted on the boiler is..pilot unit (works) a control box when i turned on the circulating pump a grey switch inside moved. that no longer is the case...near that a small box with a red button (like a reset button) pushed it nothing happens...wires from the control box to round black unit that controls the damper automatically. i manually opened the damper....3 other boxes mounted to pipes controlled by thermostats...there is power to these..any help before i call in a professional would be appreciated: The button that you pushed is the reset for the flame safety that makes the boiler follow a start up procedure and looks at the fire to make sure it is on. The boiler should have some gas pressure switches on it that often go bad, check these. Also, the damper and other items need to be in the correct position to have the boiler purge and fire. The blower also has a pressure switch on it that is a permissive for firing. There is also a high temperature limit someplace on the unit too. If you are electrical type try to follow the schematic and see if you have power in the circuit. Turn everything off, power down and then turn the power back on and start through the start up sequence. Follow the schematic with testers to see which switch or whatever is bad.

Q: I bought an electric egg boiler, which can boil upto 6 eggs at a time. The temperature at which it cooks those eggs is not mentioned.Is it safe? I mean, will it prevent salmonella poisoning? I will be eating hard boiled eggs not the runny ones.: Yes hard boiled eggs are safe unless you leave them sitting out for a week.

Q: I'm in my GCSE year at school and have found a vocation in renewable technologies and the environment. I'm currently doing some work experience for an environmental consultancy firm and just want to start learning as much as I can about energy efficiency etc. Anyway, I'm still pretty new to all this and wondered if you can tell me how gas is used in the average home? Does a house itself have its own significant carbon emissions, or do most of these just come from the power stations supplying the mains?: In anything that uses gas which properly burned, the result is H20 and CO2. If there are additional elements in the gas, such as sulfur, which is normally taken out before the gas is put in the pipe line, there may be oxidized products of the elements. It goes up the vent into the atmosphere.

Q: My Utica Boiler has some tubing coming from it. (It's been in place about 3 years and working fine.) But, we've noticed some small bumps/bubbles on some of the tubing and unsure whats causing it or if its safe..... ?? Anyone know about this thing?: if you are refering to the metal vent pipe that carries the exhaust fumes outside or to the chimney,,it sounds like it is starting to rust out from the inside...is the pipe new with the boiler or re-used from the old boiler?...does the pipe increase in size much from the size it is where it connects to the boiler?...newer boilers are higher efficient than the ones they replace,,usually around 82% or so...the exhaust gases are cooler exiting the boiler than previously,and therefore closer to their dewpoint,,so single wall vent pipe doesnt last as long,,esp if for some reason the boiler cycles are short,,not alowing the vent pipe to heat up and evaporate the initial condensation... bably best to have an hvac check it and advise you if there is a problem........dan

Q: my landlord opened up the ceiling in the hall outside my apartment to work on the electrical wiring. it has been a month now, and no one has closed up the ceiling yet, so all the wiring is exposed. the gas boiler is in very close proximity to the wires. is this a hazard?: Tell your landlord about your concern and yes if it is hot near the wires and they are just romex type of wiring they are not rated at a high temperature near a boiler if it is more then 140 degrees and if the boiler is hot at that point it can cause the insulation of the wiring to break down. They should be removed or ran in conduit to protect them for the heat and if ran in conduit it should be a higher rated wire such as THHN the highest rating wire gets and that is good to 194 degrees. Would be better to re route them and get them away if not fixed soon. Drywall does act as a fire rated wall and takes the heat out to some degree.

Q: I have an oil-fired, cast iron boiler and I believe the relief valve is what's leaking.. There is a small copper pipe that comes up from the top of the boiler and bends down the back.. at the end of the pipe it's open and water is dripping out constantly like a faucet. The PSI on the gauge is at 10! I turned the temp down to 150 degrees Farenheit and I have relieved the pressure numerous times over the last week in every level of my house. The water dripping out of the pipe in the back of the boiler is very hot and it's steamy and my basement is turning into a lil pond! Can someone tell me what's wrong???: The seat in those safety valves gets hard, and once 'popped', won't reseat - replace it with another of the correct psi, but why did it pop? is your inlet pressure regulator bad, or has your expansion tank diaphragm breached? I once got into an argument with someone about how much water weighs, and how much column pressure I needed to make the autovent on the 3rd floor actually work to discharge air from my system, truth learned, I needed 24psi at the boiler to overcome the total weight of the water. The boiler core is rated to 50psi, so I replaced my TP with a 30 psi., solving the problem. LESSON? Even the licensed boiler guys can't prove they got an A+ on the test, and in the process of 'erring to the side of caution', create new headaches!
